In short
After being cheated on, it's normal to find trust hard. Fish For Singles suggests waiting until you're dating to meet someone rather than to prove something, telling healthy caution from suspicion, and letting trust build through consistent behaviour over time. A free, confidential sexual health check is sensible, and Relate offers counselling for individuals rebuilding their lives after an affair.

It wasn't a verdict on you
Being cheated on often comes with a voice that says it must have been your fault: not attractive enough, not interesting enough, not paying enough attention. That voice is understandable, and it's wrong. Someone else made a choice to deceive you. Whatever else was going on in the relationship, the cheating was theirs.
You'll probably still go over what happened, and that's part of getting through it. But it helps to keep two questions apart: what you'd do differently in a relationship next time, which is worth thinking about, and whether you deserved it, which you didn't.
When you might be ready to date again
There's no set waiting time. A better sign is why you want to date. If you want to meet someone and enjoy their company, that's a good reason. If you mainly want to prove you're still desirable, or to show your ex you've moved on, it may be worth waiting a little longer.
Other signs you're ready:
- You can talk about what happened without it taking over the conversation.
- You can imagine trusting someone, even if it would take time.
- You're not assuming everyone new is lying.
- A quiet day without a message wouldn't send you spiralling.

Healthy caution or old wound?
After being cheated on, your alarm system is understandably sensitive. The trick is learning which alarms are about the person in front of you, and which are echoes of the last one.
| Probably a real red flag | Probably the old wound |
|---|---|
| Their story changes, or doesn't add up when checked | They took a few hours to reply |
| They're secretive about basics: where they live, their work, whether they're single | They have friends you haven't met yet |
| They push to move fast, or for money or private photos | They want an evening on their own |
| They won't video call or meet, ever | They're friendly with an ex they share children with |
| They get angry when you ask a simple question | They didn't post about you on social media |
When you're not sure, ask calmly and listen to the answer. Someone worth trusting can handle a straightforward question.
Letting trust build
Trust is built through behaviour, repeated over time. You don't have to hand it over on day one, and asking someone to earn it gradually is healthy, not paranoid.
What tends to help:
- Watch for consistency. Do they turn up when they say? Do their words and actions match?
- Say what you need. "I'd love a quick message if plans change" is reasonable and specific.
- Notice your urges without obeying them. The urge to check a phone or social media is a feeling. You don't have to act on it.
- Don't make them pay for your ex. A new partner can be patient with your past, but they can't be punished for it.
- Give it time. Trust that grows slowly tends to hold.
What to say to someone new
On a first date, you don't need to mention it at all. If it comes up, a sentence is enough:
Example: "My last relationship ended because they were seeing someone else. It was hard, but I've done my thinking and I'm looking forward now."
As things become more serious, it can help to explain that it's made you cautious, so your partner understands your reactions. Our guide to what to say about your past has more example lines.
A sexual health check
If your ex was sleeping with someone else, it's sensible to have a sexual health check, even if you feel fine, because the NHS says many STIs have no symptoms. Clinic staff can advise on when to test. NHS sexual health clinics are free and confidential, and staff won't tell anyone, including your GP, what you discuss without your permission. You can find a clinic on the NHS website. It also makes the conversation with a new partner, when the time comes, much easier.

Social media, your ex and the other person
Being cheated on often comes with a pull to keep looking: at your ex's profile, at the person they were seeing, at photos of a life you're no longer part of. It feels like getting answers, and mostly it reopens the wound.
Things that tend to help:
- Mute or unfollow, at least for now. You can decide later whether to reconnect. Most platforms let you mute without anyone being told.
- Don't look up the other person. Whatever you find won't explain what happened.
- Keep it off your own posts. A public comment about the affair can follow you into a new relationship, and into any arrangements you still share.
- Ask friends not to pass on news. Most will understand straight away.
When you start dating, the same instinct can turn towards a new person's online life. Looking someone up once before a first date is sensible safety. Checking their every like and follow is the old wound talking.
Getting support
You don't have to work through this alone. Relate offers counselling after infidelity, and you can go on your own if your partner cheated and you're no longer together. If you feel low most days, can't sleep or keep going over it, talk to your GP; in England you can also refer yourself to NHS talking therapies. If you're struggling to cope, Samaritans answer on 116 123, free, day or night.
If the cheating was part of a wider pattern of lying, control or threats, that may be abuse. Free, confidential help is available from the National Domestic Abuse Helpline in England on 0808 2000 247, Live Fear Free in Wales on 0808 80 10 800, 0800 027 1234 in Scotland and 0808 802 1414 in Northern Ireland, as listed by GOV.UK.
Staying safe online
A bruised heart is exactly what romance scammers look for. Be wary of anyone who is unusually understanding very quickly, declares strong feelings within days, or steers the conversation towards money. Never send money to someone you've met online. Our guide to spotting a romance scam explains the warning signs, and our safety page lists the reporting lines.

Questions people ask
Will I ever trust anyone again after being cheated on?
Most people do, though it can take time. Trust usually comes back gradually, through someone behaving consistently: turning up when they say they will, being open about their plans and not making you guess. You don't have to trust a new person fully on day one. Letting them earn it is healthy, not paranoid.
Should I tell a new partner I was cheated on?
Not on a first date, unless it comes up naturally, and then in a sentence. As things get more serious, it can help to explain that it's made you cautious, so they understand your reactions. Frame it as something you're working on, not a test they have to pass, and avoid asking them to prove they're not like your ex.
Should I get an STI test after being cheated on?
It's sensible. Many sexually transmitted infections have no symptoms, so you can't tell from how you feel. NHS sexual health clinics in England are free and confidential, and staff won't tell anyone, including your GP, what you discuss without your permission. Getting tested before a new relationship also makes the later conversation easier.
How do I stop checking a new partner's phone?
Notice the urge and ask what you're afraid of. Then say it out loud instead: 'I find it hard when I don't hear from you for a whole day, because of what happened before.' A good partner will help where they reasonably can. If you find you can't stop checking, talking it through with a counsellor can help a great deal.
Is it a red flag or just my anxiety?
A useful test: is it about something they did, or something your ex did? Lies you can check, secrecy about basics, pressure to rush or a story that keeps changing are red flags. A delayed reply, a friend you haven't met yet or a quiet evening are usually just life. When in doubt, ask calmly and listen to the answer.
