anyone have experience with adult 18-19 children. Separated 8 months filed for divorce 3 months ago. Dealing with severe alienation tactics by my STbXW telling my kids it’s ok to not talk, see me etc. my youngest 15 refuses overnights because my ex says it ok to. My other child who is 18 in college hasn’t spoken to me in 3 months and I did see her XMas morning. Both kids agreed to come to my house for the afternoon to see extended family today. 30 minutes before my 18 year tells me through my ex thy she is not coming. I am the sole bread winner and completely support my STBXW and 18 year old.
I am considering just the legally required college, room books etc and taking back my car and credit card. She is putting in no effort and claims mental issues with me, but posts plenty of happy pictures with my ex, her family and friends, etc.
anytime I want to talk to her or like today have her spend time with my side of the family, she can’t

I know divorce is hard but I’m not stupid and tired of unequal treatment. Anyone have similar problems?
