So I've been seeing this guy who is a lot older than I am, but I really enjoy being with him and the sex. But I recently found out he is actually dating another woman, most likely closer to his age. We never really been on a date, more like just talking and sexual stuff. I told him I liked him, but I don't know if I should continue this with him or not. Like what if he is just using me? He isn't having sex with the other girl. But if I like him, should nt I pursue him?
