Just to give background - My ex is a dickhead. An abusive arsehole, sees the children every couple of months when it suits him, argues over everything, ticks every box in the covert narcissist handbook. He met someone and married her a few months later, introducing her to the DC as their new stepmum. Moved 200 miles away to live with her and consequently barely sees the DC. Never mind, we are better off the less he is around - but. The constant emails about contact where he is changing this or that, cancelling, announcing which weekends and holiday dates the children will be with him (not asking, announcing..) - in every email he copies in his new wife, writes 'WE will have the children' and 'WE will pick them up' and are all signed Kind regards, Wanker & MrsWanker. It irritates me but I am trying not to rise to it, but I really don't want to include a total stranger into a conversation about our children, I don't know her, and I don't see how contact arrangements have anything to do with her. I have had very little contact with her apart from a couple of emails from her where she ranted that I was being unfair and unreasonable blah blah blah. Is this common, should I just accept it as one of these things and chose my battles although it's weird, right? I live with DP but I don't get involved in the contact arrangements he has with his ex wife.
