Sink clogs are firmly in the "she can call (and pay for) a plumber" camp, IMO. Especially if, as I suspect, you'll be paying child support for some time. And especially where, as you've suggested in the past, you were a Mr. Fixit-type during the M. You're going to derive a lot of benefit from not staying stuck in old patterns. And, truthfully, so will she.
Gordie -- my W's favorite phrase in that I-can't-handle-my-guilt zone is "Children are resilient". It's like fingernails on the chalkboard for me. I seriously want to scream whenever she says it. Some children are. Some aren't. Some perfectly great co-parents still manage to parent children who don't do ok w/r/t divorce. And our spouses have no idea how it's going to go, they just can't face it.
