Elle,
You are absolutely justified in being angry about this, in my opinion. My own parents helped my marriage to survive financially in a really big way, and i still walked away with nothing. It seems there is nothing like fairness for us, women. I’m so glad you are doing well enough now. But I would be pissed about the house and the coddling his parents did and are still doing. It makes sense of your situation, sure, but made your life a living hell, financially, while married. I’m so sorry. Best wishes in this season! Maybe try to focus on how happy the kids will be about it all. I’m not sure how else this will be processed well. Thanks for writing!
