They may recognise that they've put themselves and the two of you in a co-dependent situation, but don't know how to say "this isn't working out" and maybe help you two figure out a way to leave for your own place. They may not be able to articulate what they're feeling due to fear (of what might happen if they kick you both out), anger (at feeling trapped), guilt(over feeling fear and anger), frustration (that they cannot do anything to remedy the situation), etc. much as you and he may be feeling.

Is there a third party, i.e. minister, counselor, etc. who may be able to sit down with all involved and help one another to articulate and LISTEN well?

Also, I would suggest you both go to a Work Force Center and see what training they may have for suitable jobs. I have a real problem when someone tells me they can only do one particular kind of work and only in this amount of increments. I know about your health challenges, darlin', so please do not feel offended. Just know that there are always at least three choices, not one, not either/or, always a third one out there and, quite possibly, more.

Communication cannot be stressed enough. In writing, in person, on the phone, however, but get folks to talking, honestly, openly, and where they feel safe. In this case that should probably be away from the home.

Good luck!
