Hello gentlemen, long time reader first time poster.

I'll do the TL;DR up front.

I've been divorced for 2 years she had an affair while I was deployed, I came back fast forward 6 months I tried to work on it she was just happy I was a dumbass. I decided I couldn't do it any more and started the divorce process. Well luckily she took so long to sign paperwork that I ended up drawing up the divorce decree myself from New Mexico she agreed to all terms which were $500 in child support no spousal spousal support, but I kept all the debts (~$80K). It was all signed and officialized 2 years ago and have been going just like that since.

Turns out now she wants more child support so she can have health insurance so she wants to take me to court to increase the child support amount.

We were married for 3.5 years and have one kid age 4.

My question is how bad can I get screwed in the situation, any guys been taking back for round two? Is there anything I can do the fight against this?

Edit 1: added kids and length of marriage.
