Dating Help: He says I'm "Mature but still a baby".How should I feel about this situation?

I get where he is coming from. I'm 26 and I have dated guys in their 30's b/c i am very mature for my age and i have always got along better with older people, and not so much with my peers, like it seems you do too. BUT there is something that is always amiss there. I think your "Boyfriend" or whatnot is right, you may know a lot of stuff and be very mature but you still haven't experienced life like he has. That is what sets me apart from the older guys I have dated. That life experience. Keep talking to the guy but be open to others too, i think what he is doing is looking out for you and he has a good point. You may be mature, but you are still so young and you need to experience life right now. be young even though your peers are annoying and not in your league. get to know yourself right now, that is most important. good luck
