Apart from the ‘hello & welcome’ I won’t repeat the above. I’m so sorry to read your current unhappy predicament
Two (of many) threads on personality change, resentment etc are:
You might find this:
gives you some insights in how he is feeling which MAY? help?
Also pointing out to any “you look well” commentators the there are many hidden neurological/ psych-/ emotional impacts for ALL the #StrokeThrivers (?) family
Maybe asking the GP for assistance for BOTH of you (in different ways) is also called for?
And also ageUk, altziemers society that have common support needs so have suggestions & networks
At less than a year he is relatively early in the stroke journey but that’s not really very comforting I guess. However it & what you’ve said does say YOU need support. The groups above can suggest & local groups often provide respite breaks - which may do you both different sorts of good.
There is more here but this is probably enough for now
