Hi, I don’t know where to start, and my head is all over the place atm. To cut a long story short my ex of 3 years, father to my 2 children introduced his new partner to our children. They met her 7 weeks ago. My youngest asked her if she is step mum and she replied yes. He is 5. He came home after only a few times meeting her, telling me he was in her tummy!, also was begging me to let her be step mum when I was trying to explain she is daddy’s gf. I’m distraught, he’s confused and my older daughter is stuck in the middle. She has already moved in with him. Relationship with dad was controlling and I’m paranoid he’s continuing control through manipulation of the children.
