<human>: Summarize the given text in a few sentences.

Throwaway - I have been free from an abusive marriage for over 8 months (separated for 1.5 years prior) to a angry pathological narcissist. During the divorce I racked up over $150,000 in debt paying criminal and family law lawyers as every dirty trick in the book was thrown at me, just so that I could maintain a relationship with my child. 

In the end to finally settle everything and not pay additional attorney's fees I conceded a lot, even agreeing to pay $30K in order to sell our house that plummeted in value.

Now, as part of our settlement agreement it was set up that alimony would not be paid until our house was sold to provide incentive to get the house sold. at a specific value based on the ex not receiving alimony. As a result child support was calculated without the alimony factored in. 

As a final piece the wording of the agreement stated that the child support would readjust once alimony was to begin being paid because the ex would have additional income and I would have less. 

fast forward to when alimony was starting to be paid and the ex refuses to communicate on the subject (I still need consent for the courts purposes). After a few months I file to enforce that part of our agreement, 3 months later she files saying she need MORE money then she is getting now.

Legally I have the upper ground, I have made a fair and reasonable offer to settle everything based on state law in this area, but she still wants more $$$

I'm at the point now where the attorney's fees are getting to the point that it would cost me less to just pay her off. The problem is that I took that approach with the entire divorce. I want to stand up for myself, tell her no, and go to court, but I already have so much debt that I can't help but consider the financial impact. 

There is no reasoning with this person because of the narcissism, I just don't know how to ever get rid of this problem.
<bot>: Crazy Ex is manipulating the system to get more $$$ but it is unfortunately becoming cost advantageous to let her. How much should I cave in?
