Mini story time: We act like a couple!

I’ll try keep this sort and sweet...

Theres this guy we’ve been close for years he’s seen me date other people and what not, nearly a year ago we fell out, he pushed me away because he caught feelings and didn’t want a relationship. We became friends again (it wasn’t a major thing). He’s always there for me we have sex but we also have times where there’s no sex just hanging out walking his dog. He’ll do cute relationship stuff and I just adore him. He knows I like him I know he likes me but he doesn’t want a relationship. He doesn’t have sex with anyone but me he doesn’t go on dates. I don’t have sex with others but I go on dates to make myself feel less for him it doesn’t work and he knows this. He’s career driven atm and I’m just besotted by him! I don’t know what to do, I like what we have so I don’t wanna push him away again cause we’re both happy doing what we’re doing but on the other hand he’s the only man I want!!!

Help, advice please???
