In January, we got back together and things we a lot more serious between us. However, here is where it becomes quite grey. We never talked about it or explicitly stated that we were exclusive. But we were telling each other we loved them and stuff. And it got to the point where it just felt like we were exclusive like she would tell me things like how she used to sleep around and I changed her.
Yesterday, she let it slip that she had been sleeping with someone recently and after a lot more questioning, I found out it happened around Valentine's day. By this point, it definitely felt like we had a proper relationship going on. But since we never had the talk, I'm not sure if I can really be mad at her.
I asked her why and she told me she was mad at me and sleeping with the other guy was to get back at me. I honestly feel like after she said that, there definitely was no going back. Its one thing to sleep with someone because you felt lonely but another to get back at me or hurt me.
She's now telling me if I truly loved her, I would forgive her and get back with her because she's forgiven me when we fought and I hurt her. I'm basically telling her that I still love her and as much as I want to, we can never get back together because it'll never be the same. I just want things to end on a good note.
Am I being too cruel or am I fair to stand by the decision I made? I really miss her and do love her but I can't stop thinking about her and the other guy
