I think I have feelings for my ex best guy friend

We were so close everyone thought we were dating but he didn't like some of the choices I was making when I got out of my 2 year relationship (it wasn't anything bad, I just had a friend with benefits) and he felt that he was being replace because I was spending a lot of time with my friend with benefits so he replaced me and we drifted apart. 
We haven't talked in maybe a year and a half but I really do miss him, should I hit him up? Or just let it go? 
Btw, I'm not one to contact someone who is no longer a part of my life, I've never done it before, I don't give second chances and that's why I wouldn't usually ask for one.
