I've been dating this guy but he told me that he has 3 other girlfriends including me and on one of our dates he asked me to talk to one of the girls and I told him no. Also, he has told me stories about them and stuff and allowed me to see the text messages they've sent him. I'm wondering why he is telling me all this, if has he says, that I'm his girlfriend. Do you think he genuinely appreciates me or should I stop talking to him?
