LBH w/ a WW trying to save my M (4)

[gs9]

Mr Bond,
Thank you for pointing out the attitude of resentment. I've spent some time reflecting after reading this. I have felt a lot of resentment for her this weekend. Luckily she wasn't around. So, I have to ask myself....how do I feel? What is my attitude? What am I portraying to her in our interactions?

I desire to show an attitude of confidence and boundaries. That I will no longer be bullied, disrespected and run over by her. That I am moving on with or with out her and that I am good either way.

This morning I told her I was 95% sure I wanted to keep the house. She then said she wanted to keep the house. Initially we had agreed to sell the house but the paperwork has not been filed yet.
She asked how I could afford a new truck and house payment and that I must be making more money than she is aware of.
I said " You know how much......" She interrupted me and said "I don't know how much you make..." and continued going on about commission and bonuses and demanding to see statements and paystubs.
She then said " are you going to answer my question?"
I said " I began to answer your question but you must think what you have to say....." She interrupted me again and said "I don't think what I have to say is more important."

I said " I began to answer, you interrupted me, maybe we can talk about it later."

She continued to demand I answer her questions a couple more times. I got D4 ready for school and ignored her demands. She left for work.

Her interrupting has been a long standing issue with us. I have told her numerous times that when she interrupts me in mid sentence I feel she doesn't care enough about what I'm saying to let me finish. I find it disrespectful and rude. She says this is how conversations work and she is not interrupting she is interjecting. I am not concerned with being right or which of us is right. I know what is right for me and how being interrupted makes me feel. I feel this is a good boundary and one that is important to me.

If I am wrong or I handled this interaction wrong someone please let me know
