I dont want to be gay please help?

I am homosexual. I like men but never tried before. There is a guy I like and he is bisexual. He is hot, good looking, life of a party, outgoing, social, gets tattoos, does MMA boxing, the typical straight acting guy. I love him physically but not emotionally. I think I might be afraid because he has a past history of cheating on his girlfriends, he is an alcoholic and he is making a lot of friends with people I have bad relations with from high school. However, I met a really nice girl. She is attractive as said by a lot of straight guys I know. She is kind, friendly and compassionate. She is very smart. She gets the As and Bs in college courses. She is a church goer and I feel a connection every time we have a conversation. I am like the guy version of her because we have so many things in common and we get along. I love her emotionally but not sexually. I really dont know what to do. The guy I like is so different from me and I dont think we get a long as much and even though he is hot now he wont be 20-30 years from now and I cant think of growing old with a guy. However this girl is a straight man's dream girl. The perfect wife and mother material. I see a future in her and I know we can raise a good family and live an idyllic lifestyle and please don't tell me there are other guys because I live in Hawaii and its island fever, its such a small island and it would be so hard for me to find another guy I like that is not straight. I am very picky
