Thanks Steve85 for your reply. Sounds like your situation was as bad as mine.
Yes, I did a lot of talking - for all the good it did.
I don't know how else to burst her bubble. I'm buying her out shortly and she will move into an apt and then in with him next spring. Initially she was going to move right into his house but she said with renting an apartment it will be easier for the girls to transition.
And get this - OM has three kids two of which are twins about the age of my kids.
My kids will end up sharing a room with each other and they don't exactly get along. WW attention will be split five ways for all the children.
I don't want to sell the house - I just finished decorating the kid's bedrooms and their friends like to hang out here.
Can you think of any other bubble bursting ways?
Also, OM doesn't live in the school district so WW will have to do a lot of driving. I told her she can't pull them out the schools they go to.
