My boyfriend or girlfriend cheated on me, should we break up?

You should talk to your partner first. Don't make decisions when you're angry. Try to calm down first and talk to him/her with an open mind.

This is your choice. However, before you come to a conclusion, think carefully whether you believe this person is worth it or not. After all, no one is perfect, people make mistakes.

Only you can decide if breaking up is the best approach if you think that the relationship is not salvageable.

yes, cheating is shit man, like that's shouldn't be tolerated, cheating is horrible and it hurts so many people

Ask yourself, would I rather be alone or with someone that doesn't value me?If you find yourself making excuses for why your partner cheated, stop right now. People CHOOSE to cheat. Go separate ways and give yourself a year. Then evaluate the situation.

How close are the two of you? Can you resolve conflict? What is a one time thing or a pattern? Do you know people that have worked through similar things and come out stronger eventually?

In my opinion an experience, "once a cheater, always a cheater" so I don't really tolerate that kind of stuff.

it up to yours love and attitude of partner , if just mistake , you can open your heart and forget , you can continue in love , everyone in life have mistake so sometime can forget , but if you cant forget , or your partner dont change , may be yours love have some problem , and think careful if can't resolve is break up can be a solution

Breaking up with someone or staying is a very personal decision. If it were me, I would not stay with someone who cheats on me because I feel they would do it again if they did it once. I usually make myself pretty clear from the beginning of any relationship and tell the person if they want to cheat then they are not for me. If they cheat once then the relationship is over. That way if it ever happens, the person is never shocked that we are going our separate ways. Not everyone thinks this is a deal breaker and some couples work through infidelity. Its a very personal decision.

Think about your future, ask yourself many questions. Can I ever forgive? Will he repeat it? Is he worth the pain I took? Does he regret it? And any other questions you see necessary; then you'll be able to judge by yourself.
