A few snippits from your post:
| He said this was because he wanted to finish his degree with his friends. |
I have had some health issues lately and he has not helped me at all during this.
...he has not lifted a finger to help me he says that he knows I need help but he is not able to do anything.
It is very difficult to get him to be intimate or affectionate with me. He tells me that it's not me but that he does not have the desire for it.
I am going to go out on a limb and say that you are probably paying for his education as well?
I don't see depression here. But, unfortunately, I do see what looks like someone that is taking advantage of you.
If he cared for you, he would move with you, and not stay where he is to "be with his friends".
If he cared for you, he would help you with your medical issues.
Why won't he "lift a finger"? Is there a medical issue involved? Is he incapable for some reason? Or is he just lazy?
If he was really depressed, he wouldn't go to school, he wouldn't "hang out with his friends", he wouldn't be doing a lot of things. Depression affects everything you do, not just certain things.
If he's still able to hang out with his friends and go to school, but doesn't do things when they pertain to you or your marriage, then he's most likely not depressed.
Like I said, unfortunately it sounds like he's just taking advantage of you.
I would ask him to see a counselor now. If he's true to your relationship, he will. If he still wants to wait until he finishes the semester, then he's just dangling a carrot, and will find another excuse when the semester is over.
