He Wants What I Don't Have

It's becoming apparent that my Hus and and once best friend, wants to be with men. He prefers cock over pussy. It's been months now that he completely ignored and denied me with any real passion or sign that I still sexually attractive to him. He constantly searched twink porn and would rather me peg his ass then mention or try making love or even fucking me at all. Hes been putting up front to hide the fact that I've caught in to him being pretty much gay, and will use me to get off. Of course he loves to do that, I have an amazingly tight and pretty vagina and even sweeter and tighter ass I always allow him to smash. But after the 30 seconds of passionless pumping and him cumming.. And leaving me high and dry as usual... I'm still dumbfounded to why he wastes his time with me. It's only starting to hurt me emotionally to watch him be so unhappy trying to convince he wants and loves me but clearly doesn't. I love him to no ends but no one is happy doing this anymore and nothing, not even a baby will change it. I'm always left alone.. He's always doing something to pretend to be busy so I can't see how much he doesn't want to be here. How much he wishes he was somewhere else and with someone else. He hates everything I say or do.. He hides everything from me. Lies to me and is bad at trying to act like he wants to be with me. I don't understand why he stays. He tells me more then not how easily he can up and go but won't. Obviously it's confusing and I don't know what else to do. I'm just sad and lonely all the time.
