"Wife" blames me for her losing custody of our daughter

I was awarded cstody of me and my soon to be ex wife's baby girl. She blames me when the reason I won the custody hearing was because of shit she did. This all started with my 16 year old sin coming to live with us because he walked in and saw his mom had slit her wrist and killed herself. He was a huge mamas boy and me and him didn't have a close relationship. We do now though. My wife just seemed to hate him for no reason and say things to him about his mom being dead. Last straw was when she ripped the wire out of his headphones and threatened him just because he didn't hear her ask him to wash the dishes because he has his headphones in. I told her never threaten him again, she asked me to choose her or my son and I picked my son. She hit me in the face, nothing I'm not used to and took our daughter. Between then and the court hearing she sent my son messages about how he ruined the family and he's trash like his mother, he should have killed himself with his mom, the threats. I showed this all at court. Maybe she would have had a chance at 50/50 if she didn't threaten teenagers. She gets supervised visits once a week, has to pay me 283 in child support and we are finalizing our divorce soon. Besides that my son is building a relationship with his baby sister and his moms Ash's are abuve the fire place with a picture of them both. I'm planning on surprising him with an Urn for his mom. So everything worked out in the end.
