What do I Do???

So basically I posted a few days ago and I'm still unsure if I am 100% gay but my best friend who I love in every way knows that I do. He has stayed my best friend and always tells people that we are best friends. I hug him all the time and tell him everything and he tells me everything. He says he likes girls. Does anyone think he could be gay or bi or is he just a really good friend?
