Am I crazy?

So last summer I went on a little vacation with my girlfriends. Still in the same country just about 7 hours of where we live. ANd while I was there I met this really gorgeous guy! I was 18 and he was 22, which at first he thought was bad but then he said he coundt resist me. I loved that! I dont want to sound cocky but it was really nice to hear. So all we did was make out because I didnt wanan have sex with him, since I only knew him for about a week. So after I left, we remained in contact through email and such and we discussed being together and stuff and I explained to him my concerns about our age difference and the whole sex issue. He seemed to be very understanding and agreed with what I said. Now its almost been a year since I've last seen him, and since about 2 weeks ago I cant stop thinking about him. I cant get him out of my head. I jsut want to be with him. The problem is that we live far away and also he has a girlfriend, but I know that hes only with her cause shes leaving to go back home in the summer. So jsut for the fun of it! Am I crazy??? whats going on with my hormones? Some advice would be nice!

all you need to know is that you are in love and if he still loves you and you love him thats a feeling so your not crazy your just in love everyone gets this feeling when they are in love and you have got it
