One ?..
Have you asked... well more like told... him that if he refuses to do anything for you that you will be leaving him?
I only say this because thats what I had to do, mine never realized how much it bothered me, and he thought that I was "just nagging" him... now he does the little things I ask and we couldn't be happier.
But if he still ignores everything then, yes, dump the loser
