If you still love him and want to be a part of this marriage, then go for full-time work, and ask for help at home, so that the children are more secured. When he realises that you are going for "equality", then he will shift and change and see that he needs to also do some of the housework and cannot escape then.
If he is only concerned for himself, and his work, and kind of see you as a slave in the house, and not even support you by giving suggestions or to fund the help, then he is only really quite selfish and is looking after number one. Or rather, he sees work as all that, and everything and is not seeing the world beyond work. It depends on how high a position he sits and if he is the kind of man who wants a "little house wife" at home, that kind of setup.
I do not know what is normal or not, but the big question is, if you ask, then I think that is not your "normal". Questions to me means doubt. You have to ask yourself what it is that you want out of the marriage and the relationship. This is one of those scenario that is pretty real.
Higher paying jobs, means more stress, does not necessarily equate to happiness for the person on an individual level. And if you and the children are not there, then there is no justification for him to earn more.
You really have to ask yourself honestly what it is that you want from this marriage and how do you guys see the future together, and start opening that kind of discussion for talks. If he avoids this kind of talk, then I dare say that he probably is too scared to truly talk about things.
To be honest, as a bystander, I would think that this area is pretty sensitive as well. Since considering that if something has taken a lot of effort to get to at a certain stage, then nobody would like to rock the boat if anything. It really depends on what you want, and start to make changes in the relevant areas. Take back that control in your marriage and life in general I think.
