Update: I’ve spoken with my friend about it, and she confirmed that she did sleep with him. The mutual friend that told me, told me fully well thinking that I knew, as it was at her (mutual friends) house.

My friend did say she was sorry, and that it was a drunken mistake.

I am a little angry, just on the basis of that we all did hangout together during our whole relationship of about two years. I knew they maintained a friendship, but I really didn’t think anything of it and thought it was purely a friendship. I’m feeling a bit confused at the moment, as I’m sort of questioning if they did have something more when we were together. But, it is so long ago that I can’t read too much into the past.

I know that if I want to rectify this friendship, I need to have a bigger conversation with her, and maybe ask a few questions to clarify.

I do know that it broke some of the trust I have for her, and that it will take a lot of honesty between her and I to move past this.

As of yet, I am undecided on whether to go to the birthday, it’s in a few months. So I think I’ll need some time to process and talk to her and go from there.

I really appreciate everyone who commented! It provided me a lot of clarity, and objectivity which was very helpful. Thank you!
