Partner resentment

Hi I wonder if anyone can help. With increased appointments and my son needing constant supervision I have had to reduce my hours in work significantly. My husband has always been supportive in the past, we have been married nearly 20 years, but now seems to not help around the house "because I do less hours" spending lots of money of golf etc "because he earns it" making digs about me not doing as much as him?!?! Has anyone else had anything like this. Im hoping it will settle because diagnosis is very recent and my new work hours still settling.
