RT, I do understand how your D is still suffering over all this. I think all our kids are, just that people in RL think we're going through a "normal" split up. But ours, is the gift that keeps on giving. The song with legs that you hate but keep hearing in your head. I'm sure you've already told your D that there are many kids, the kids of us on the forum, who are having very similar experiences to her.
My S12 was crying this morning before school, (couldn't get him to go, actually) because he says he hates his life, that he's been sad all year, that his dad is going out with a 30 year old and doesn't want to spend any time with him. I just validated him. I listened so he could vent, told him his dad doesn't even know what he's going to do himself on a daily basis, and that he should try and focus on the good things in his life. Hard when you're feeling down. Maybe our kids could do with a little dim contact, too, so they don't feel the immediate effects of their dads not remembering the details of their lives, not caring that D might not like seeing OW rubbing his feet. I mean, does anyone like to see anyone rubbing a guy's feet?
My D just graduated, too, and it's a sad milestone with the dads more into their horse faced girlfriends than them. Shining Star, I loved your description of the OW. It's much more respectable than the names I would like to use, and although I love horses, it's not a good look on a girl! Think I might start using the name for my H's OW.
Three years is just the beginning of the end, right? This is a world of its own, with different rules. I hope your D gets through this down cycle.
