I'd say we were both very reliable, but W was usually the one to volunteer at the kids' school, schedule doc appts, make sure they had what they needed....but since BD, she's dropped the ball. For ex, we have a shared calendar online for bills, kids and school. I don't know that she even checks it anymore. I've been making sure kids get picked up, dropped off, make doc appts..she wasn't even aware S15 had a doc appt the other day. When the kids go to her place, all they do is watch tv (they tell me). Then they come home with all kinds of homework. It's like she's in her own selfish la la land. Even her best friends have told me that I'm basically a single parent.
