Sounds like you may need to have the locks changed. How dare your H not respect that as YOUR home, not his.
And I was frustrated when I wrote the above entry! Actually the house IS in HIS name. We agreed in the divorce settlement that he could have liberal use of the house, but he was supposed to give me 2 hours notice. He hasn't changed his address so bill, etc come to him at this address. I need to work on setting boundaries!
