This guy that I used to hook up with fairly frequently has been messaging me on Instagram a lot. I've been kind of entertaining it because it was fun but I realized he has a girlfriend and has been posting her. He recently asked to see me later at night (obvious booty call) and I asked him "don't you have a girlfriend" and he just never responded and kept sending me memes… It's been really on my mind lately and I just don't know if I should say something to her. I took screenshots of everything just in case. I'm sure I'm not the only girl he's doing this with ugh. Do I reach out to her?
Update: I told her!
