Give up or keep hanging in there?..

Almost 4 years ago I met his boy, from the moment we met there was just something between us, and we both knew it. we were both very very young though, and things just didn't worked out. time passes by and we remain very close friends, than we started dating again.. I was going through a lot at home and verything was falling apart at once.. I got scared and pushed him away.. he was heartbroken. He gets a new girlfriend, we stay good friends. even though he has a girlfriend we always feel that there is something more between us. I knew for myself that I was still madly in love with him.. we just joke around and leave it for now, because of him and his girl. Than a couple of months ago him and some friends stayed over at my house, He was giving me small hints that he still liked me, and eventhough I thought I had gotten over him I realised that even one year later I still liked him alot.. I get myself together and decide to kiss him.. our first kiss, it was so sweet, and you could just feel the chemistry between us. He ends it with his girlfriend, what I thought was a good sign.. I saw him a couple of times after that, we had one really nice evening together and I just fell for him all over again.. Now I'm sitting here, and nothing is really happening.. I would like to know what's going on, but everytime I give a hint that I like him it kind of stays unanswered.. But then he turns around and says he misses me, that he is afraid to loose me and loves me.. I don't have a doubt about the fact that he likes me, but does anyone have any clue about what our problem is.. I'm getting kind of desperate because I don't want to loose him again.. but for one reason we just don't seem to reach the next level between us.. Anyone any advice or experience to share?

Thanks.

First dont dwell on the fact of losing him. Dont work on impulse. Dont try so hard not to lose him, it may end up differently. Yall shouldnt dwell and make of what yall most have. Just ease up and dont be afraid to tell him anything. Let him know you are truly there, just be there for one another and everything will be fine

I think you need to take a leap of faith....
for me I think the choice is either...
wait for your answers, which may be forever or
you can find a way to reach them faster...
but really listen to your heart and let it guide you
