To have or not to have : when is the question?

alright, me and my ex are getting back together. and now are officially together. we went out last weekend with all of our friends and publically showed...affection. but just for background information, we've done everything but . i would *love* to loose my virginity to him because we've been through so much together and i've never liked anyone more than him. but here's the thing: we both want to have BUT i just want to make sure he's in this for me, not for . he says he doesn't want to date officially boyfriend/girlfriend thing because his bestfriend does that and they never hang out because of it and he doesn't wnat to become like him...and he thinks it's articficial and that everything falls apart when you put a title on it. we've talked seriously about this all and he's even brought up if i was really into him because i kept questioning him if he really did have feelings for me. so i think he cares but i'm not sure. also, we hang out every week and generally hook up/make out/go around all other bases...but is deffinately in the mix now. he said he won't pressure me and will wait but last time he said that he left me. out of coincidence, yes, but none the less, i can't help but be worried about that. i told him that once we've been together for a week it wouldn't be a problem, as long as he proved he cared about me. what do you think about all of this? love, your fellow 19
