hlp me

I cut things off with my friend with benefits and now really fancy this guy I'm in a theatre company with. His girlfriend just broke up with him after lowkey cheating on him, but we've been flirting and have been really close for the past month or so. I don't know if I should make a move soon or whether I should wait for a while before taking a step. Help, I like this guy so much, I'm horny, and I don't know what to do!!!
