Ex-h lives 10 miles away from where the kids and I live. They are at an age now where their activities largely happen at weekends - sports, etc. They go there EOW and He always tries to arrange it so that even on his weekends, I have to do all the ferrying around. He's never once watched them play in a match, to the point where he will drop them off at one and drive off instead of staying to watch.
If they never went to his, I wouldn't mind doing it all alone, as I could plan for that, but I often work on weekends when they are with him. The combination of changing match/training times and his lack of cooperation means they end up missing stuff and he tells them the reason is because I wasn't prepared to pick them up and take them.
They never do anything else "worthwhile" when at his - just sit at home doing nothing much, which he says is his right because it's "his weekend". But they are teenagers!
I'm finding it really hard to know what to say to them. As background, their dad also pays no maintenance at all, as he says he has no income. But can afford to support himself quite comfortably apparently without a job. I work full time.
AIBU to expect him to take an interest in his kids' interests and help out a bit?
