You should also attempt to understand what his "rotten from the beginning" complaints are so you can start making the changes in case you missed some. He sounds hopeless and grumpy in general. Is he depressed? That can make people more verbally abusive. If you mention that possibility to him, he may think you are judging him negatively. I can't imagine it going well. But it is something else for you to consider as you look at the whole picture. If he's going to therapy to blame you, is he still going to be depressed in a year when you're gone and blaming some other situation?
