Tell him or no?

I really want to be with my ex😩 I can’t get him out of my mind no matter who I talk to. We have a messed up past and most of it is my fault. But, it’s been about 2 years since my last big fuck up (lol) and we’re good friends, we hang out. I get a flirty vibe from him but I usually overthink things so I don’t wanna assume.

I just want to tell him I want to be with him and see what happens, but I’m so afraid of him rejecting me 😩 I can’t even think about it, my heart would be broken but I know it’d just be karma.

Sorry I’m ranting but I just don’t know what to do!

Tell him I love him or wait it out as friends?
