I kicked ExH out 2 1/2 years ago when I found out he was having an affair with a girl from work. DD was 12 at the time and stayed with me. He moved in with the OW and DD (understandably) didn't want anything to do with her so ExH would take her out for a few hours every weekend, as long as it didn't interfere with his and OW's plans. It was obvious to DD what had happened to cause our split and she wasn't happy about this. I've never poisoned her against him though.
Eventually, DD and OW found they got on OK and now DD's closer to OW than she is to ExH! He treats her like a child and has no idea how to deal with her, having only seen her for a couple of days a month for the last 2 years. He does no parenting, just moans at her for being a stroppy teenager (she's not when she's with me).
So the problem is that she hates going to see him and when he dropped her off yesterday they were so rude to each other, so I'm wondering if there's any point in her going at all? I've told her, and she agrees, that it's between the two of them to sort out whether they want to continue seeing each other and that I won't interfere but I will support her as long as she's being reasonable, and advise her when she's not.
I hate seeing her so unhappy though and feel like they're destroying any relationship they might have. As I said, I'm not going to interfere but would be grateful for anyone's experiences of situations like this and any advice on how best to help her have a better relationship with her dad.
