Strokes can change personality. This may not be him talking, it may be the damage from the strokes. He must have a neurologist, yes? YOU need to talk to this doc to find out if this is a medical problem, or if your husband is just upset/depressed by what has happened to him and is acting out. In either case, he won't be comprehending that he has a problem, so he is unlikely to go to any doctor on his own. He may not understand why he is feeling the way he is. You owe it to yourself, and him, to figure out where the problem is coming from, and then decide if there is any way to fix, adapt to, or deal with the problem, or if it is time to let go of the unfounded guilt you feel towards the idea of abandoning him, and take care of yourself as you deserve.
