Sorry to say this turtle, but if you want to know how much of a twat your husband really is, I read your opening post absolutely convinced that you were trolling (and badly at that) - then I saw you had a profile etc.
please read the rest here in the context of my being quite a fierce woman (so I appreciate it might be a bit OTT)
If it were me I would express some milk, pack a bag, sweetly hand over baby and tell him you are off for a bit and will see him in 48 hours. AND leave the mobile behind. Go to nice hotel. sleep. Go home, make him cup of tea and ask him if he managed to get any laundry done while you were out.
The less extreme version is to force him to tell you how many hours he is willing to commit to relationship each day. And nail him to an answer, 10? 5? 3? and make a point of ranking it in terms of.... so Gym hours per week = 12, salsa = 16, relationship = 5. Then list the hours you are doing. housework x, baby Y sex Z, yourself.... 0 I guess. Then ask him if he considers this to be a reasonable split. If he says no you have the basis to start renegotiating these hours. If he thinks he is right then you need to take him to relate and discuss exactly this list with them. Any macho arse will squirm at this. Benefit of writing these hours down is that you can keep a nice list on the fridge where you put down what he says he does against what he actually does each day. Be pointed about it. Discuss it with his parents when they come to visit. Maybe give it a title 'reward chart' and sweetly tell him if he gets 5 gold stars in a row you will go down on him. Time to humiliate him and when he accuses you of exactly that, tell him that's exactly what he has been doing to you for last 6 months.
Or kick him out and tell him to come back in a week if he is willing to change.
Sorry but the guy needs a wake-up call and will carry on getting away with it for as long as you let him. Tell him that at the moment he is adding no value to your life whatsoever and behaving like a 3 year old. And tell him that if he really doesn't get that then you are better off without him so that you can have the freedom to find a decent man instead of putting up wiht a petulant boy. Which is all true by the way,so you may as well follow through if nothing else works.
I seriously think that things will not get better unless you up the ante, big time. He is miles beyond being able to take in something like those babyproofing books. If you don't do radical stuff then you will have to put up with this for a long time. The baby will get easier after a bit but your resentment won't. If you up the ante there is I guess a chance of doing irreperable damage to the relationship, but is the relationship as it stands worth maintaining in it's current form?
