Is it normal that i still want to be with my possibly gay/bi friend?

I have been friends with this guy for about 2 years even though it seems like we've known each other our whole lives. He is my best friend. I've had other long relationships in the past but none like this. He is my everything. We talk about getting married and having kids and he's told me that he has always felt that God had put it on his heart to be with me forever and I feel the same way. The only problem is that he had a relationship with another guy. He tried to get out of it multiple times but the other guy was his friend and told him that if he ever left he would kill himself, so naturally my love never left even though he still always thought we were meant to be. We recently discussed this for the first time, even though i suspected it for months. He told me that he is just confused because before this guy pulled him in with all these lies, he never had any homosexual feelings. He's always been physically attracted to women. He told me he wants to be with me and still see's us together with a family in the future, but as long as the guy he was with is around we cant be together. There is just a big wall there. We layed together for hours talking and held each other and rubbed eachother and i even made him hard by just rubbing his thigh. Im so in love with him and he has feelings for me too. Is this normal? Please help us!

oh and the guy he had a secret relationship with is my ex boyfriend of a year and 7 months who claims to be straight but told my love that he is busexual. Could it also be that I'm only attracted to gay guys?
