Last week my ex husband managed to manipulate me into taking my baby to his mother’s house. She hasn’t seen or had contact with me or my baby since February. My ex demanded he take her to see his mother in her house for 10 mins so I waited outside in the car. Time was passing so I knocked the door and said baby needs to come home now. Ex MIL said are you not coming in and I said are you joking (I have serious issues with her and she is partly to blame for the breakdown of my marriage). She slammed the door and locked it with me standing outside and my baby in the house. I ran to the car to call the police and a few seconds later she shouted that baby was coming. My ex went mad at me for being so angry with her but I don’t believe I was wrong to be mad, it felt very threatening. AIBU? I firmly believe he should have sided with me, it was an awful way to behave.
