So I've been dating this guy for about 2 1/2 months now and we have planned to do a lot of stuff together. Like go to NYC together for a weekend to visit my family, etc. but we have yet to make it official... I've asked him and he says he's not ready for that step. We are completely exclusive and hangout only with each other in our free time. We basically are in a relationship with out the official titles. I also have this irrational fear that he's only hanging around for sex, but he is putting a lot of work in just for that, if that's the case. I just need advice on what I should do. Should I push for a relationship? I'm just really confused...
