Are you becoming resentful that you cannot expect things from him? Can you let things go that are his alone? Like I mean if you expect him to do x and he does not do it, do you pick up the slack even if it only effects him? I know you have a child (children) so that does limit some of the ability to just say forget it all.
Some things may slide if he will not do his part - can you let them slide is the question I think.

For example laundry - if he will do laundry great. If not, and there is not an exchange of duties that he fulfills, then your laundry and your child's - you do - his is up to him - if he does not have clean socks or whatever - it is his problem, not yours. (this is just an example and may not be the sort of thing you are talking about)
