Help, I have a guy from my past that I think I am still in love with..but

[Cami]

he has a g/f and seems happy.? This guy is from high school and we have been out 6 years. He chased me and told me he loved me and all this from like freshman year til like 2 years after we graduated. We were always friends and I was so scared if I were to date this guy it would mess our friendship up. But then he started dating another girl and it was a huge change because he had never dated anyone because he was too busy chasing me. So When he started dating this girl, I didn't know what to think...I had so many emotions. At first I acted like I was fine but after a while I couldn't. I finally broke down and told him how I felt, that I loved him and wanted to be with him. We talked and everything, but he asked why I hadn't said something 6 months before and that he was happy and thought she might be the one he would spend the rest of his life with. This literally broke my heart. During the conversation he told me not to give up on us and don't count us out just yet....well that's been about a year ago and I have dated someone since but my mind always goes back to not counting us out. I still love him and I mean I love this guy too but I always go back to me and this guy and wonder if I would have just spoke up sooner if things would be different....I need some advice! HELP!
