tension with best friend

so my best friend and I used to date a couple years ago but split up because it just wasn’t the right time and we wanted to focus on ourselves. we stayed best friends and recently have been growing a lot closer again, to the point where we have some romantic tension. we hang out all the time, we FaceTime most nights, and he even spends the night at my place, sleeps in my bed with me, and cuddles with me. We also will kinda flirt with each other and give each other kinda sexual compliments and stuff. I don’t want to date anyone right now, so I’m perfectly ok with where we’re at and just enjoying being with each other and doing what feels right, but I do acknowledge that there are plenty of things that aren’t platonic. The thing is, he just said a couple weeks ago “you already know my boundaries, I like platonic but we can hype each other up.” But his actions and comments absolutely haven’t been platonic at all? I trust him and know he’s a kind, caring person who is mindful to never take advantage of anyone, but I’m just worried that none of those things meant anything and he was just horny and I happened to be convenient :(
