<human>: Can you give me the gist of the text in a nutshell?

12 years ago I won custody of our child in the state of North Dakota. I was granted sole legal custody of her, she was granted visitation with the stipulation she never have the kid on consecutive weekends or more than 3 days total. There was some abuse issues against me AND the kid, and her ability to make decisions was put in question. 

About 5 years ago baby mama got knocked up and subsequently married. 4 years ago, after allegations of abuse and questionable decision making, divorce was granted and full legal custody with similar visitation to mine was given to bio-dad for this human larvae too. 

Bio-dad, fearing baby mama's batshit crazy tendencies, cut bait and disappeared, off the grid. Baby mama had the bright idea to go back to court and won full legal custody of the new human larvae by default because bio-dad is off the grid and never showed. 

Now, the issue is following that landmark victory, landing full legal custody of a human larvae she doesn't actually have possession of, I am hearing rumblings she is starting the process of wanting custody of my child. 

So... what am I looking at? Does she have any grounds to even do this? Do I need to lawyer up?
<bot>: shit mom granted no claim over my kiddo, wins custody of another kiddo based on a technicality, now wants to try to get my kiddo, what is my future looking like for me?
