I totally agree with you. In fact, I'm prepared for her if she says she wants someone to move out.
I'll simply tell her, she has enough money in her savings to afford a place for 4-6 months and if she thinks her leaving would give her the time and space she needs, then she should go.
I'm not the one who needs space, so honestly, I'm not leaving. The state of Arizona has my back on this one as I don't have to leave my own house.
Thus, don't worry, if anyone is leaving, it is her and my D and I will stay here and move forward.
