Jenni, I'm really interested in how your new attitude will affect him and you. Putting aside the leaving him question, I'm wondering whether you told him you wouldn't be doing his work before he chose to leave, and he's now testing your boundary?
How would it have gone over if you had just refused to leave a house you're happy in? Moving house is so stressful it can't be good for you to have done it 5 times with him, especially if he ducks the hard work.
Congratulations for separating your financial affairs; you won't regret it.
