Hi stu, My X tried to sell the house out from under me. I guess that if you dont want to sell it, dont.
I think that Christmas is going to be a blessing and a curse, yes it is a good chance for you to show some of the changes that you have made, but it also could be a chance for some things to go not so well, and if it kills you to be around such a classic family situation, then dont do it. If you are going to have a hard time with it, then dont do it!
Maybe theres something to be said for letting her have her separate life, and all that goes with it... including separate Christmases with your S.
I guess I gave the wrong finger to the wrong man...
