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

yes or work it out, communication is key in any relationship. Talk about it, and maybe see a therapist together. If nothing works...end it.

If you believe that you can't trust them anymore or you don't feel comfortable in the relationship than yes. But it is okay if you want to work things out and try to save the relationship.

If they cheated on you, you should break up because it shows that they don't take the relationship seriously enough

You should talk about it with him/her. Discuss the possibilities also. But, what you decide to do is completely up to you.

It depends. Most likely, this will haunt you in the relationship/lead you to care less. You need to be open with your partner about what happened and how you feel.

before making any decision, you should take time to think about every possibilities, ask yourself first, whether you are taking a right decision or not.

You should focus on yourself, give yourself the value you really deserve, the love you really deserve.. get fullfilled. get emotionaly healed.. once you get it you are ready to move on...remember "New good things only comes to your life when you get rid with the old and bad ones"

Yes, because if your partner is cheating on you it is a sign of disrespect and the relationship not going well. Would you rather date someone who is willing to cheat on you or someone who will not think of dating anyone else and you are all they think about?

It depends on if they truly do feel bad about what they did. You should only break up if you feel like the relationship isn't worth fighting for.

No but it can be yes, depends on the situation. People commit mistakes and it is just a prove that we are human beings. If your partner cheated on you, you have the right to be mad or to be angry. But would you waste all the effort and love that you both have just because of one stupid mistake? People and everyone deserves second chance. If it is the first time of your partner to cheat, then i think your partner derserves your forgiveness but im not saying that you will just forget and forgive. Maybe try to figure things out and know why did your partner commit that mistake. But if your partner did it for several times already, i think it is better to let go and move on.
