I don't know what to do?

Stuck living with CLL, living with a 13 year relationship X partner. He has not been there for me AT ALL since diagnosis 1 year 9 months ago. He has been ignoring, and avoiding me all the time (On and off for the last  couple of years.) If I talk to him he just wants to argue (Very similar to a Narcissist?) I don't work as I did plan to start my own business after passing my diploma 2 years ago now (I unfortunately used all my savings up to do the Diploma course.) I feel I am going crazy being alone, and living with a past boyfriend. (He just gets takeaway meals, and eats in his bedroom, he goes to the launderette to wash his clothes. He was talking to me for a while (which was much better. But that all stopped again. If I see him he normally gives me a filthy look. I have had enough with learning to live with CLL, and also having to live with an x partner who is too immature to just be friends.

Oh God! I just don't know what to do now? I have rang samaratans several times (Who are brilliant) have had NHS Psychiatry which has ended due to the NHS can only afford so much (Which I understand.) 

I wish I could just sell up, but I know half the money from our house would not  be enough to get me a roof over my head. 

I just don't know what to do? I have no family, and no friends?
