Wife was annoying, ungrateful, selfish, etc.
I don't understand how she can complain about domestic issues while he is putting his life on the line infiltrating a dangerous criminal society, severely conflicted by both his job and his conscience.
I get that she doesn't see him anymore but she really had to take a step back and put it all in perspective. Donnie said something to this effect in that counseling scene, he was absolutely right.
What an ungrateful wife.
