get over him

Alright long story short: I’m fwb with this guy (let’s call him C) have been for a while. He’s a cocky asshole who thinks he’s cool but he’s not, he’s insecure, he’s annoying, immature, and cares too much about what other people think, and I want more than that. (Not saying he’s a bad guy, I’ve just outgrown it). So I haven’t talked to him in a while, and am talking to a new guy who I actually like (let’s call him T). He’s great, a bit older, we work well. Only problem is, I’m still physically attracted to C. I’m not with either of them, so it’s fine, but I really want and need to get over C. I need to move on. I thought I had, but when I see him it still effects me. Any advice ?
