I'll point this out and let you digest it for awhile. You say your husband has loved you like no one else, and in the same thread you say every problem is blamed on you/your condition and that your husband dirties the kitchen and living room with things anyone with common sense would know do not belong there--and on top of it, those things are preventing you from having a social life.

It seems to me if your husband was truly able to solve his own problems (his lack of a consideration of you, his filthy habits, and his mean-spirited abuse of you by blaming you for your condition) he would have done so by now, huh?

Regardless of the past, start now the way you mean to go. Get the car parts out of the kitchen and in a designated spot that guests don't have to see--the garage, the basement, a spare room, a little shed you'll purchase. If he asks why you have done this, tell him what you have said here: you want the house to be livable for both of you and to be presentable for guests. If he pulls any blustering, tell him a rational person would know that car parts don't belong in the kitchen or living room.

Stop taking the blame he is dishing out. Once you do that, it will reveal your next course of action.
