So a few days ago I made a post regarding my past girlfriend possibly hooking up with other guys while stating that she "still loved me". Now I realise getting hung up over the situation was wrong of me considering we weren't in a relationship any more and she can fuck anyone she wants. However I really quite like her still unfortunately so the oneitis was heavy. I haven't talked to her in the last few days at all and decided to just try and move on, however today she has been messaging me like crazy. I haven't replied or even read any of them but I'm unsure of what to do. Do I just act like nothing happened? Wait and reply with 1-2 word responses and act like I don't care/not interested in her? Or ask? And if I ask and she says she didn't sleep with him, then my gut feeling is not to believe it, but that doesn't mean she's lying. Sorry If this comes off as a shitty post or whatever (since it's pretty trivial) but I just wanted to see opinions. Thank you.
