I too have the same problem with a guy and i still dont know exactly what to do
i know exactly the what you mean(really and im not just saying that like some people do)
what I would/what im doing is just not thinking about it as much kinda being open to what happens (in my situation i dont think he is gay/bi now which is dissaponting) so you know how everyone tells you if you losse something then to find it, stop looking for it (I dont know but it works for me) so thats what im doing but it is really up to you and what you think is best
