I NEED HELP ;_;

Ok so I though I would come here and ask and I have asked other people but I though this is a perfect place to ask this and please don't call me anything mean or bad ;_; becuase I don't know what to do so here is my problem: I have a boyfriend and I like... Him he tells me he loves me but he also tells other girls that he likes them and I'm somewhat of the jelous type and I don't think what he is doing is good but anyways I met this guy online and I roleplay with him and he has told me that I mean something to him and he wants to get to know each other and someday maybe go out but he lives somewhere else but I really like him so what my question is what should I do stay with someone who is (13) and he might dump me when he gets the chance or a (16) year old who keeps telling me he really likes me and wished I live near him he has even told me he loves me I don't know what to do ;_; sorry this is so long I type when I'm nerves or freaking out ;_; ;~;
