I texted her an appology this morning.

Any suggestions on what to say when she asks me to leave?

Prior she said she would leave and take the kids too. then she said how could you stay here and make us leave. I said I wouldnt let that happen and just wanted her to have to deal with what she is doing.
Now I dont think I should leave, BUT how do I tell her rationally?
I did say, (before she suggested her leaving), that I wanted to stay till we are divorced and have things figured out. She didnt like that.

I do plan on using the 'how is this help me reach my goals approach' before I speak. Emotions take over.
