When you find your partner cheating you, should you divorce immediately or let it go and give a chance of recovery?

you speak of 'partner' and of 'divorce', implying that they are 'married'..
If my partner/husband cheated on me, I would think he's made his decision and mine would be to leave.
No discussion.. no recovery.

once is cheater is always a cheater
life is to short for recovery

Depends on many things.. How much this relationship means for you, on if you are ready to fix the relationship, if it can be fixed, on the needs you have, on the needs other one have.. and the list is long, only you know better what is right or good for you. Anyway an important note is this if a person have what needs from a relantionship, is unlikely that will cheat. We are all very caught with ourselves too much nowdays, and we forget to walk in another person shoes, sometimes is not bad to asking yourself I'm that partner that other person needs?Must be equal somehow what you ask with what you give.

Did ever think to ask the question why did He or She cheat or even why do people cheat

If you have been cheated on....you walk away. Unless you are desperate and want to reconcile, for the lack of anything better on the horizon. Trust issues will always be present, no matter what!If you can live with that...go for it.....you are a better man than me Gunga Din......just saying....

stay and collect proof.
apply said proof in justice system
then GTFO after you make sure your assets stay yours, and burn all bridges for about a dozen different reasons.
Then Post her name so the other men will know.

Hai

You should forgive them, but you should also be bold enough to walk away from them. Why live with someone and have doubts about them? Why sit at home and wonder "is he/she out banging someone else while I am sitting at home watching the news"? I know that when you commit to a relationship that most do not want to let go of it (maybe fear of being alone, or you convince yourself you can change that person) but why waste time with someone who decided that it was okay to break your trust? Again, forgive the person but also be brave and go back out into the world looking for someone who falls for you.

I'm probably stupid enough to give them another chance, but after that, they don't get a third one.

There is an saying "Fool me once, shame on you. Fool me twice, shame on me." I have found I can forgive some mistakes and recover but cheating on marriage is a gutless selfish act and if I forgive someone that then I am endorsing that behavior and betraying myself. I can live with a lot but sticking a knife in my own heart is just to stupid and unacceptable. Especially when it betrays those who have loved me and suffer my humiliation if I allow it. The worst punishment you can invoke on a cheater is to survive and thrive with out them.

I agree if you are married, hard for forgive, especially when that trust is broken. Been there, had my heart ripped out, tried to forgive, but found she was just stringing me out to hide her assets until she felt she had enough to leave.

But how about if you are just dating and haven't really said you committed to each other but one side thought you were committed but the other wasn't sure and hooked up with another person? Had this happen to me as well, about 7 months into the relationship she hooked up with an old boyfriend, didn't tell me until a few months later. Said it was a one time big mistake, will never happen again.

Forgive and forget?

Good explaination.

You seem like an engineer. Because you do engineering analysis of the problem.

I've been cheating on, it has been terrible experience. I don't understand why? No need to do that...just be bold enough to end the relationship.

I don't believe in second chance
