In love with my guy friend...should I let it go?

We met when we were 14. We chilled and had sex through high school. Kept contact with each other after I left and ended up having sex again last year. After the first couple times we had sex raw a few times. I know it was a stupid decision, but I’ve always liked him & he’s always liked me so I figured maybe that would make him like me more

Fast forward to this year he tells me he loves me, has always loved me & that I’m his. He also revealed that he thought about me a lot and I was always on his mind. The thing is, I’ve never felt the love I’ve felt when I’m with him. I can tell he loves me but we’ve never made anything official. I’m so comfortable around him & I honestly love his energy. When he visited town a few weeks back he slept with me in the bed no sex and we cuddled all night, it was the sweetest thing. I’m very emotionally unavailable on a general so this level of intimacy with someone is incredible.

I don’t want to press him by making him commit to me, and I also don’t want to start a relationship just in case it possibly ruined the friendship. He always makes me laugh & he makes me smile and I get butterflies when he’s around and I think about him.

I’m so conflicted! We’re only 21 so we’ve been knowing each other for 7 years straight but he’s watched me grow from a little teen to a woman. My heart is so attached to him.
