lost and desperate think she has closed Part 2

[along]

Now the W is texting me about how long I will want her to pay half of the mortgage. She was really persistent and wanted to know when the refinance would be done and she wanted me to know that this arraingment was not OK with her, since she was not living in the M home, even though she acknowledged that it is our debt. Again I believe she is getting advice from the OM. She is making it out like it will be a financial burden. She makes 12 thousand more than me for a year so I don't see a burden on her. I am the one with the burden picking up all of our bills and mortgage. This is really not allowing me to go NC since I cannot ignore these texts. Have been taking my time in responding and trying to validate when I answer.
What should I do?
