HELP ME BRO

Im not sure if this is a vent or advice seeking because to me, theres really no other way to approach this but get over it. 😭 Ok so basically, this guy that ive known for years confessed to me a few weeks ago. I initially rejected him but we got closer since he confessed and now.. I kind of like him?? 

The problem is, im still struggling with my sexuality. I dont know if im Bi or Lesbian, all I know is that I have a preference for girls. Plus, he wants to be in the military when he grows up and he's christian. 😭🙏 Im athiest and I don't like the military at all. I want to talk to him about it, but it feels selfish? 

Idk what to do, but hes supa cute and genuinely the best guy ive talked to. Hes funny, really fun to be around, smart, respectful, and bisexual. Idk why I added bisexual but im hoping u guys understand the appeal in that LMAO
