Ex wife is crawling back after 6 months of no contact. Claiming she has rights to more money and property.

Divorce was finalized in March 2023. In February of 2023, we both signed a legally binding agreement determining equity allocation of our martial home before it was sold.

As background, when we purchased our house back in March of 2022, we used some of the life insurance that she got from her grandmothers passing as a down payment. When we separated in September 2022, our house was on the market until about February 2023 when it sold. During these 4 months or so, I was covering the mortgage because my ex was unemployed. We agreed to accept the lower house sale offer in February so she could get her portion of equity. I was willing to wait to see if the market got better, but knew she needed cash ASAP since she was broke. We agreed upon our separate portions of equity and signed off on it in the legally binding agreement. We then divorced officially in March 2023.

I am thankful that I had the hindsight to create the legal agreement regarding the house equity, since I know her crazy ass would come crawling back.

My questions are:

Does she have any leverage to get the money back after the fact?

Is this her fucked up way of reaching out and seeing how I am doing? Testing the waters per se? I am happy in another relationship and we are actually expecting a child this spring. I suspect she might have heard about this through mutual friends and is upset with the news.
