Just stayed the night with my now ex, went through her male "best freind" snaps with her and found videos of them fucking when she stayed the night at his. I only checked this because I was sus of her staying at her best freinds house who she also happened to be ex's, and after she told me how much weed he gave her aswell as buying her dinner that's when I knew something was up. I asked her about it the morning after she stayed their and she lied through her teeth, and I believed her like an idiot lol (this was days ago, I broke up with her this morning after I found the snaps between them)

It's important to mention I don't believe she was in full control, I believe her ex who she trusted took advantage of her, but from what I know she didn't actively try to stop him after. I still feel bad for leaving her like I did, but I don't think I can ever put this past us out of self respect.
