Living with Testosterone Deficiency

My story is my husband is not interested in me. Weather it be sexually or not. He would rather spend time up in the bedroom smoking and watching tv and not be with the family. I am very lonely and he says that he is not happy. We have went to counseling and that does not seem to work. My mother’s friend suggested that it might be testosterone deficiency However it is called. My husband has had a quadruple bypass surgery at the age of 38. He is taking medicine for depression and it has helped out tremendously with the grouchiness but not with being loving and wanting to be with me. When we fight, he can be great for the first couple of weeks and then back to his normal routine. Who knows what is wrong with him. He is working a lot lately and I can understand if he is tired but he has to take a nap every weekend for 2 hours and without it he is grouchy. I think he also sleeps at work but won’t tell me because he is embarrassed and thinks that I think he is not working hard. It seems he has tons of testosterone but he is small and has very tiny legs but a lot of hair. I don’t know if this is the same problem as testosterone deficiency He is able to have sex if I want to but he hardly ever wants to. He is grouchy a lot and is not lovey like I want him to be.
Any input would help. Signed almost Divorced.
