I've been dating a serial cheater. There are a fewer women he sees now than when we first met. He started introducing me to his friends and mentioning me as "my girl" in text to his friends. It seems I climbed a ladder and now I'm at the top of his lovers' list. It wasn't my intent. I don't want to commit as long as he sees all these women. I don't mind seeing him just for fun because apart from his cheating and lies there are no problems. It'd be much easier and simpler if he admitted there are other women. When I confront him he lies though he knows I don't believe him. I'd commit if he does but it's fine by me if he didn't. When he says he loves me it sounds superficial. I don't know how to deal with him. I don't have a reason to ditch him either as it's not like I'm actively looking to get married or anything.
