So my mom called DHS on me because of a decision I made. The decision being wanting to work on my relationship with my spouse and child. Well she didn't like that and called DHS and said that me and my spouse beat each other and that we beat my son. We have never hit each other and have never hit our child. I'm so pissed that she would do something like that. Am I in the wrong for wanting to cut all contact with her and not consider her as my mom? I'm extremely pissed about it and she thinks it's funny
