My Kids Are Mad At Me

Me and my husband are divorcing and I'm taking him to court for full custody but I'm gonna offer visitation. We are a 8 month old boy, a 13 year old boy, and a 16 year old daughter. Personally I feel like kids Belong with their mother, hence why I'm going for full. When I told my kids my daughter straight up told me she wanted to live with her dad! My son too! When I asked why, they said they just want to. I told them, I'm the mom and I make the decisions and they both got mad at me. My daughter flat out said " I'll just run away". I told her to hang over her phone and she slammed it on the table.
