MIL problems!?

Please tell me I have a right to feel offended & done.

Backstory - my mother n law asked my husband for money our WHOLE marriage. when he would say no , she always said it was my fault. And I ruined him. She asked for an allowance in December since “she’s his mom and his job as a man is to take care of her”. He said no - she said it was my fault. At that point I realized I was not going to do it anymore. I stopped talking to her. Fast forward to April, we haven’t talked, but she randomly messages my husband saying how cocky I am. I didn’t entertain her drama and deleted her off of my page. She knew she was deleted because had mentioned it to his family. Now that I’m closer to my due date she texted me saying she just realized I deleted her. And I told her I didn’t have to explain myself and didn’t want drama so I deleted her after her nasty message about me to my husband. This is what I get back. She is repeatedly saying I’m “just his wife” and she’s “always going to be his mom.” She is saying I’m completely wrong for putting an end to this feud after she’s called me names, blamed me for everything, and told me at one point I’m an awful mom. But why do I feel SO bad about her saying I’m “just his wife”? Is it because I feel like I’m so much more than that?

I have high BP so I quit replying because it caused it to spike. I don’t get bothered easily but this really struck a nerve.
