My “ex”s friend

So this dude and I were not really dating but it felt like it and we “loved” each other. We don’t like each other anymore but now I like one of his best friends. That guy is not the guy people would think I like but I do. One of my other friends asked him if he liked me because she and him are close. Turns out he likes me and I like him. I have one class with him and it’s going to be awkward because we both know we like each other. The funniest part of the story is that when my friend found out he liked me she said “Looks like your getting a bf” and I responded “I’m not ready”. Idk what to do?? Help
