DP constantly slags off his ex wife. He does this to me, to his DD (his ex's daughter), in front of my kids .. to anyone that will listen.
He encourages his DD to say that she doesn't like her mother and encourages lots of negative feeling about her. I don't think this is healthy.
She's not the best role model in the world but I don't see why we all need to slag her off constantly, surely life is too short?
She sent a couple of abusive text messages to DP last week because she'd got her visiting days mixed up and blamed him. Now personally, if I had received the texts I would have either replied privately or ignored them. DP made a huge deal out of them, showed them to his DD, showed them to me, repeated them to my kids to show what a "nutter" DSD's mum is and made a HUGE public spectacle of it. He didn't however show his DD the message where the ex apologised and admitted the mistake was her fault.
If I don't slag her off he gets all offended, as if I'm "siding" with her. I just couldn't give a shit about the woman to be frank, I hardly know her and don't want to waste my energy slagging her off.
I think he's worried DSD will decide to live with her one day so he tries to turn her against her as much as possible but it's so unhealthy, he doesn't think he's doing anything wrong.
