DH has 2 DD's with his ex (age 5 and 6). All his ex has ever done is critizise me and my 2 DC (age 9 and 10). She once even said that I am a bad mother, apparently she based this on the fact that I make my DC do chores for their pocket money .
I have tried to build a good relationship with DP's DD's but every step of the way she has said bad things about me to her DD's, despite this I have managed to maintain a good realtionship with the girls and we are close.
Every xmas I always send card to DP's ex, but this year I have had enough of always trying to be the nice, reasonable one and specifically said to DP that I would not be sending her a card. I'm sick of her thinking she can just behave however she wants. I wouldn't have minded if DP felt the need to send her one as long as my name wasn't on it.
DP took my DC to town with him yesterday and I just found out from my DD that DP let her pick a card for his ex and that later on when he had shouted her upstairs it was so she could write this card out, she put all our names on it too, including mine.
I feel like DP has really gone behind my back, the way he did it was so secretive. It would have been bad enough for him to have put my name on the card but him allowing DD to do this has made me so angry
