You have my sympathies. Sounds like a bad situation.
Your offer to pay the excess is a good one.
Ignore those with no human emotions apart from greed and control. They will just bring you down at a difficult time.
I'm not getting a pathetic competition about who makes more money.
I am comfortable on my income, I'm glad yours is working out to.
We have different approaches to making money. And your the one who seems challenged by this.
