I really like this guy and we talked a lot and he was very nice and funny as hell i never met a guy like him and after that i found out that he goes out with a lot of girls and not serious at all and even so the girls love him and i don't want that i want a serious relationship what should i do?
Well he isn't for you. He is just mucking around, having fun and not wanting to commit. And you want a serious relationship with him. I don't think it will work, but you can tell him how you feel, see if the feeling is mutual, if not, well you know what to do and that is to move on.
