Step son out of control ending marriage!?!Help!
10 year old step son pulled a knife on my 12 year old daughter, I'm I right for calling it quits?
There have many problems since my DH and I got married (less than a year), we are both the only parent in our children's lives. At first step son absolutely loved me and was so happy he had a mom again, then the cuteness stopped and it started becoming strange. He began to hug inappropriately (head in boobs, rubbing his man part against us females), cuddling got weird because when would try to move his head around on my lap. I had to cut off affection down to head pats only because of this behavior, which I explained to him many many times was super inappropriate, but he kept trying it.
He would also sneak in my daughters roooms in the middle of the night and stare at them while they sleep, other times try to peak at them while they were changing, to the point where we had to install top locks on the doors. Lots of lying and manipulation to DH too, also he started being destructive like he broke our tv, he punched a door until it broke, broke another doors handle, was throwing metal object at my car, etc. one time I tried to discipline and tell him no and he tried to headbutt me. I come from a background of being abused and even though he's a child it triggered my ptsd.
Final straw was he pulled a knife on my daughter after he called her a lesbian and she called him a porno binger (we caught a couple sneaking porn of step sisters, step moms, beastyality, and rough porn). So he got pissed that she brought it up and he pulled the when her back was to him but my oldest daughter saw and stopped him. DH took him to a behavioral center for about a week, but they only diagnosed him with depression and didn't address all the other strange behaviors. My daughters are scared in our own home (previously only my home, DH and Step son moved in). DH and I got into it and he asked me what I wanted I said it didn't matter what I wanted, that I do love him but I have to protect my minor children first from harm and that the situation wasn't safe. So he left and went to his old house when I told him I didn't think this was fixable.
Am I right for ending it? am I being irrational? Or am I right to be a protective mama? It's not like it's happened over night, it's been a problem for months and I kept asking DH to address the issues and teach the boy that they were unhealthy behaviors, but DH is not a good discipliner at all, so now we are here about to start divorce and moving all his stuff out. Advice please?!
