isitme - we keep our financials separate too. I buy groceries, pay my bills like car insurance, health insurance, I'm usually the one to pay dr visits, always the one to miss work for them, and I'm usually the one who buys holiday gifts and all her clothes unless family gets her something. He does pay the house bills like mortgage and utilities but if I had the money I'd be all for chipping in. He knows that. I bring home a third of what he does. I do all the house work after work and take care of DD once I get home. He picks her up from the sitter but that's about it.
Usually he gets like this after he does something and wants me to feel as bad as he does. (He got some pain killers from a "friend" on Saturday, left one on the night stand right where DD could scoop it up if she wanted. I confronted him about it yesterday when I saw it. He was apologetic but had an attitude since)
