What would you do if your boyfriend/girlfriend cheated on you?

Leave! Don't ask why, don't try to make it work just forgive her/him and move on. Moving on won't be easy but that hurt is less than the hurt of trying to make it work and thinking about them two every time you two have sex or every time he/she says I love you

If it was my home, I'd tell them to get out and never speak to them again. I'd be done with that person the instant I saw what was going on, no excuses. If it was their house, I'd walk away and then the rest would be the same as I previously mentioned. Though the moment I heard moans and realized who it was, that person would no longer mean anything significant to me. I cannot stand betrayl, for any reason.

Wonder about how I was dumb enough to have entered the relationship in the first place... I'd probably leave and try not concern myself with it. Crying over how my ex is a POS won't help the situation in any way.

In my house throw them out right in the state they are and bother the next day with removing the stuff which is hers. In her house, just leave and never talk again to this one cheating

I don't know about walking in on it but when my ex fiancee cheated on me with one of my good friends I only managed to learn a tough life lesson and try to move on. She is kinda crazy so after that and even to this day she calls me her soul mate. Whatever that is supposed to be.
