So I took your advice and now I've fallen for him......?

So i asked a question about a month ago regarding being a gay man of 31 and dating my little brothers best friend of 25. Yes i got some great answers and thank you. However its on to phase two. Things are going well but where to go next. Chris and I have now been together for about 6 weeks. We get along great when were out, or when we see each other but at this point we are only able to see each other once or maybe twice a week. Hes got no issue being together regardless of the fact that he is one of my little brothers best friends. He's doing well coming out also he's not afraid of being out together even though were from a small town of 800 people. I think that he has all the feelings for me that i have for him. I understand that he has his two children and once obviously was with women, but now i'm concerned over that fact he could potentially leave me for a woman. He does admit that i make him happy and he has more fun with me than he ever has with any woman(not ually, we have yet to be overly intimate) Chris does however admit attraction to women. Im deeply afraid to continue this pursuit, yet am ungodly happy when I am with him. Its a frustrating situation. We've talked about moving in together but im not sure that that should happen either. I really think im starting to fall in love, and his daughters are beautiful and wonderful children. Be happy for as long as possible or fear the possibilities of what could be? (Geez are straight relationships this frustrating too) Any thoughts???
