This is easier said than done. You can not fix anyone that does not want to be fixed. From your post you both have medical issues but you only seeing the issues will not fix his end. If I had of learned this 5 years ago I would not have waisted 5 years of my life trying to help someone that says he doesn't have anything wrong with him. I went through what you are going through about the sex thing. I said I do and w did good to have sex once a month. I was told many of times he didn't feel good he was sick. But he could talk to his best friend every day 9 to 10 hours on the phone and play a computer game with him for at least 5 hours a day. This really hurt me to see what all I did for him and in return he couldn't even talk to me 5 minutes when I got home from work. My point is if you keep trying, you will just keep getting hurt and feel worse than you already do. I kept thinking if I could just show him how much life is with me in the picture I could make it work. Wrong, I could have fell over dead in my tracks and I really think he would have kicked me out of his way and walked on. It may hurt you now but you will hurt a lot worse the longer i goes on. He will never treat you like you need to be treated. I say this because if you are working and footed the bills for him to come and see you, while he buys what he wants with his money. It is so hard to see when we just want to fix things and have a happy life with someone. You may not meet someone soon, but you will one day. And I will say this, I have learned the alone feeling is not as bad as thinking you have someone and you are alone. I really hope some us this helps you and you do not have to go through the hurt as long as I did.
