If this is really just a 30 day separation, and when it's over you will be back in the house, then get it in writing. Before you do it, have her sign a piece of paper that says in 30 days you will move back in and she will not attempt to prevent you from doing that. Or whatever it is you've agreed to. And you should get a tit for tat. If you are giving her the 30 day separation that she wants, she should agree to give you the Retrouvaille weekend that you what. Working together is a two-way street. No one should get everything without giving something.
