you are NOT willing to do the alternate moving out thing, you stay in the home, don't move out, no matter what she agrees to, she can always change her mind and you'll be out of the home. No alternating between an apartment and your home, if the OM is that important to her, allow her the responsibility of her actions and let her move out and be a big girl and deal with the consequences of big girl decisions.
Seriously, no moving out for you, if she wants to, just let her move out, np, but you don't move out, stay home, it's a better position for you through all of this - trust me.
