Ugh..advice?

Hi everyone, so I have this sort of ordeal going on with my best friend that is extremely complex, so complex idk if I’m gonna be able to write everything about it. So in summary, I have been best friends with a gay guy for about 2 years now and right about now he has expressed that he definitely thinks he’s bi. We’re really close so I figured if he’d wanna try something I could offer, and I did. For the past couple of days we have been cuddling and having progressive sex. I know he’s figuring things out but hes unable to decipher if the cuddling is just him being really horny or if he has feelings for me. Honestly this is the most confusing and frustrating shit I’ve ever come upon. People have always told me we look like a great pair and I think the same. I’m writing this up in hopes to hear what kind of advice you ladies have to offer because I can feel this wrecking slight havoc on my mental health and it’s driving me insane.
