Dont be afraid to do the same thing over and over. If there is something he likes say for example a foot rub and you did it and he still upset. That doesn't mean it wasn't helpful. Maybe he would like another or just for longer. My point is there is probably things you do that are helpful just because they don't change everything doesn't mean they aren't valuable. So think of what works and do it more. It can have the effect of having two wives. Twice the positive care but no additional person to hover with nagging.
I think that you rock improving yourself to be a better mate is an awesome trait!
