Relationship mistake

So, my problem stems back from years ago. I have known this guy(im going to call him C) since we were very young, and I've always liked him. During high school we talked and were together on and off, but when he went to college things ended. I started dating a guy and we were together for almost 2 years. During the last 6 months of our relationship C started talking to me again and spilled his feelings for me, he said he had liked me for a long time and that he wanted to be together, so we talked every day while I was still dating my boyfriend. I knew I loved C, I had since we were younger but the relationship I was in was my comfort zone so I was scared to break things off. Finally when I went to graduate college I claimed I would be done with my HS relationship because I really wanted to be with C, but when it came down to I was too scared to go through it. C was livid and things changed, we talked and hung out a lot my freshman and Sophomore years of college but he had changed and was obviously too scared to let himself be that open with me again. So the last year and a half we haven't talked much, its always awkward when we are in the same place which happens because we have the same group of friends. I still am in love with him and think about him every day but confronting him about it right now wont go anywhere because he is in a relationship, its not serious that I've heard of. I know what's meant to be will happen but I'm struggling with that, I could see myself being with him for the rest of my life but I'm scared he doesn't feel the same and if he cares at all he hides it really well. I try talking to my friends about this but they all roll their eyes after this long so I need advice on what I should do, and if anyone thinks it's even worth wondering about him. If there is no chance then I don't want to waste my time but its very hard to let go when it feels right.

It's hard to tell if he cares about you like going cafe about him. .. I'm pretty sure he does though but I understand its hard for you to just say okay so do you like me out what? I think you need to wing it there for letting things just take its course. .. it's hard because you'd just love for all his attention to be on you but guys will be guys. . Take it easy don't stress yourself g over it. ..
