Well, I would be the biomom in this scenario. I did decide it would be best for difficult child if she moved with dad for one year:
1.) Got her into a different school district (having trouble with the one we were in).
2.) Give Dex and step-mom a glimpse into what I was saying all those years.
3.) Show difficult child that I mean what I say when I say it. Not that I did not before, but I had told her this would be the next step if her behavior did not improve, so it happened.
4.) To get myself straight - went into depression the year before, we struggling with patience (plus she came after me with a hammer and it scared me - for her and me).
What I was grateful for that step-mom did?
At first she for sure treated difficult child like family (not as much anymore - she now has 2 adopted sons of her own).
I have to continue later. Sorry!
