so ive made a few threads regarding my relationship, etc. heres a new one: so my gf had this guy she was hooking up with on occasion for about a year and eventually developed major feelings for him. then she went to europe, he kissed her when they met up (chance meeting she tells me...yea, right....i'm sure it was far from it), and then he stopped talking to her after they got back from the states. she tells me she was really sad over that, and that she got over it and eventually we got together. and now this guy sends her a message saying that hes in town for the summer and that they should hangout. he knows she has a bf, but a part of me cant shake that something is going to happen or will happen - becuase she had major feelings for him, and this guy asking to hangout after not really talking to her much...hits her up to hangout out of the blue. and now before i bring this up to her im looking for opinions on the matter, cuz i dont want to be that overbearing/jealous bf.
