I don't have any advice for you to get over your jealousy... but I can say that it's really important for you to do so before it gets out of control. I'm having a zillion problems in my relationship right now and it's all because my boyfriend gets out-of-control jealous (he constantly checks up on me, starts screaming in my face, pushing and shoving, not allowing me to have any guy friends at all etc..). A little jealousy is healthy if it's kept in control but don't let it get too bad! I know it sounds silly but going to a counselor can really help with these kinds of issues! For example, a lot of guys get jealous because of their own insecurities and some kind of counseling can help you realize that.
