Long story short, she was travelling out of country for a couple of months and found out I was messing around with other women. We fought over the phone, made up, but fought again a few days later and stopped talking for two weeks. Called her again, she said she thought we’re not in a relationship anymore and that we can discuss it after she comes back. A month passes, she’s back home, we get back together. She says she hasn’t been with anyone after me and so we became very serious, eventually plan for a future together. This was many months ago. Today I found out she actually did fuck a guy during those two weeks. I did tell her when we first started dating that I won’t take her back if she ever slept with anyone other than me. What should I do with her? I know that I can’t in good conscience ever be serious with this chick anymore, but she is very submissive, a fantastic fuck, good conversationalist and intelligent. I’m considering the following options: 1) break up immediately, 2) tell her I forgive her and nothing changed but actually look for a replacement while still fucking her, 3) tell her that we can still be together but from now on I’ll be seeing other women, while she still has to be exclusive with me. I imagine she will lose any respect for me if I continue as if nothing happened. Her main point is that she thought we were done and never getting back together, but after that last call after the two weeks and after fucking that guy she realized that “she still loves me” and didn’t fuck anybody else for that last month, which of course she could be fucking dozens of guys because she also had tinder installed and claims to have only used it to get attention.
