Friends with a ex?

du

Im friends with an ex from middle school. We dated, it didnt work out, he cheated. But were 22 now amd still friends. We've been like "bro" friends for a while.

BUT recently he told me he likes me. And i KINDA like him to but i enjoy being single. And i care/like him but Idek.

Hes a good guy, got his shit together ect.

And we've been hanging out more recently. But every time we hangout its like you can tell we kinda feel eachother but idk. Its awkward and and i feel bad. What do i do?
