Need advice. Wanting to hook-up with a bi/closeted guy

I recently ran into a guy I know that I used to work with that I've always been attracted to. He doesn't know I know this but he used to hook up with another gay guy that we worked with. When I ran into him he told me he had to move out from his girlfriend and I asked him for his number. I've talked to him a little bit already and I told him about how I no longer have roommates and have an apartment by myself
