KML, support money will be more than enough. I will work at some point, but may go back to school first. Lots to consider.
Regarding the mail, he needs to put in a change of address. It's annoying. However, if it gets returned maybe a note will be made on the account. I'm tired of cleaning up the mess he's made.
As far as H agreeing to my move, he has in the past, but anything with him can change. He could make it difficult, but my attorney is certain there won't be a legal issue. H doesn't want any custody and has put that in writing. It will also be very clear that if I have to sell my house staying in my area will be a financial burden. Rent is sky high and home sales are booming with bidding wars. The boys and I would be in a small apartment. I won't waste money on that. I need to think of my future. Buying elsewhere with a very low mortgage makes the most sense long term. We'll see. It's a big decision. One I was hoping to make once I got the boys through school, but I may not have that option.
