Friends with benefits.

Cameron
So me and this guy started out as just being really good friends and we got really close. Well as time passes we started being sexually active and it was almost like we were in a relationship but it became very clear we weren't. We were FWB for 10months and he was my first and I really started to fall for him even though I know I shouldn't. Well I moved away and when I went back to visit he told me that if I would've stayed and been maybe a year older we would probably be in a relationship together. I've been wanting to hear this for months now but it wasn't something I wanted to hear after I moved. I just can't get that night out of my head and I can't find a way to get over him even though I know I need to. I need advice here ladies...?
