Feel alone in my marriage

The 18th of this month my husband and I will be married for 3 years. June 22 of this month I gave birth to our 1st son together. When we were dating and the 1st yr we were engaged my husband was what I pray for after we got married my husband lost his SSI and that was hard on us financially but we learned to adapt. My husband took care of the house because he is disabled and I worked. I did not have a problem with that. Well as time went on I started having problems with my legs, I was diagnosed with rheumatoid arthritis and it causes me to have continues pain in my knees and sometime it makes hard to walk. Sometimes the RA is so bad that I can even move any part of my body without help. I still get up and go to work because my income is our main income. Anyway as time goes by I am find that the man I married is changing and not in a good way. He don't do half the stuff he use to like say I love you just because, he don't cook, clean, take a bath ( unless he wants sex), he hide stuff, acts like everything that I do gets under his skin. I cry more now then I did when I was single. I am not perfect but I try to be the best wife. I tell how much my check is, I tell him where I go, I ask him if I can hang out with my friend and family. I ask him if people can come over. I took the lock off my phone because I have been accused of cheating a lot of time. Every time I try to talk to him he apologize, say I am his heart and he change for just a week or two. When I try to have a conversation with him like we use to he pulls his phone out, look at TV or start talking to the baby. If I get mad then he's like what's wrong with you? I have done all I know to do, I went to counseling, I've read books, I have increased how often we have sex ( because he said if we had more sex than he would be able to do more stuff because he not back up)... I just don't know anymore. Since our son has been born he don't even sleep in the room with me, my son and I sleep in the room together and he sleeps in my son's room or the living room. I apologize if it not easy to read but I am just filled to the rim with frustration😢
