That's what my mom did to my dad.
She then moved her lawyer into the house my dad built. I was 13 and I asked to live with my dad. My mom's boyfriend lawyer motioned in court that I be psychologically tested to determine if I was 'competent' to make such a decision at 13. He claimed in court that my dad had 'warped' me against my mom.
Before I was allowed to live with my dad in a two room apartment after we were exiled from our own home, I had to spend my 8th grade summer being psychologically tested by a weirdo in birkenstocks and black socks.
Ah, so now the picture becomes clear...;-)
Just kidding. From what I've seen you weathered that storm.
