If I left tomorrow (don't want to, love him dearly etc...) I don't think my DH would have the first clue. He'd be floundering around like an idiot with everything.
He's very good at doing 'chores', cooking, cleaning etc... but yup, I am the one who has made all decisions re nurseries/childcare, who sorts out all the money, I know where all both our money is all the time, make sure we have enough in the right accounts etc.... he even gives me his details so that I can do his online banking. Just easier- especially now he is the only one working. I sort out all the paperwork for anything, book our holidays, make sure the house is stocked with the right things, that the children have clothes, bla bla bla.....
I feel very much like my DH supports me entirely and does his fair share, but I am just a bit of a control freak, and know that I can just keep all these things under control and sorted better than he.
I suppose YANBU if you are tired of being the grown up in the relationship,..... but does your DH actually know you feel like that?
My relationship with my DH has developed the way it has because I am happy to do all that stuff, and he is happy to let me! I am sure if I turned around and said 'ugh, you sort it for once in your life', he probably would....
