I am bi, how will I act with my BFF?

I am a boy, and I am bi. I know my BFF for a long time, but I never let him know the truth. The problem is that my friend is going to study aboard. As a BFF, I want to hug him so much, it's just that, nothing more. But my BFF is str8 and he hates gay, bi, etc people badly. I know that my BFF is attractive, yet I never want to have or in relationship with him because he has a GF and I don't want to affect his future. I want so many things like asking him to stay over (because I have so much to talk with him), a hug, a farewell party,... but I don't know how to act like a normal person, what should I do?
