Why does my husband set himself up for a nag fest?

Is being a Nag so bad?Does it really depend on what you are nagging about? My husband sets himself up for a nagging so he should not complain at all. He does not take the trash out but agrees he will do it, so guess who does it? He will make himself tea and leave the tea bag and sugar on the counter when all he has to do is through it in the garbage 2 ft away, which i think he avoids so he does not have to think about taking it out. I ask him why he does not throw away his tea bag and sugar wrappings, he tells me he is trying to make a profound statement! which is that i should get up in the morining and make it for him! He complains i nagg him and tells me to shut up, that i am stupid and that i am also a bit2#!! I want a seperation, i think it is best.. what do you all think about this nagging problem i have?
