I am fairly new to this, so I don't know if this is the correct space to reach you, but I couldn't help but notice your sitch, the age diff between you and H is the same as mine. I also believe my H is in MLC.
It is encouraging when I see that you are now in MC and he has just started AD. Does that seem to be helping? Prior to DB I was begging H to go to MC, which he has refused. Several of his family members are on AD and it really seems to be making a difference.
When I read your posts it gives me hope.
Most of us are about as happy as we make up our minds to be.
