Well, I'm a FT Stepmom Now...
You read that right.
Eternal Teenager voluntarily handed over custody of YSS.
Without giving away too many details, YSS had a mental health crisis earlier this week. DH now has him in therapy. ET is also dealing with having to move ASAP, so she and her DH are moving about an hour away to somewhere they can afford.
All of this has had DH prepping all week for a potential battle with ET about YSS living with us. She beat him to the punch. She's taking YSS EOWE, she is giving up CS (per the state calculator, she would owe less than $100/mo and it's not worth the fight), and she, OSS, and YSS are currently packing up YSS's stuff to deliver here.
DH and I have a lot to discuss, both with each other and YSS. But, as of now, I've entered full-time stepparenting.
