Should I even try to work things out with my husband?

here's the deal, we've been together since I was 14 years old, i'm now 31, he is an ok guy, he does some stuff well, but i am forced to do the majority of the work in the relationship (i.e. pay all the bills, do all the laundry, wash 95% of the dishes, 95% of the cleaning up, take care of the animals, make his doctor appointments, attend his doctor appointments, go to the store for all errands- he won't go alone, keep things going in the bedroom and work a full time job) He is also very selfish in the bedroom, often my needs are not considered at all, usually only once a month or less, although we have at least twice a week. I make an effort to do things that he enjoys, in the bedroom and as far as social activities, but he does not make the same consideration. I have tried talking to him, he tends to deflect everything, and if he does make an effort to change it only lasts for a short while before everything goes back the way it was. He is also occasionally slightly emotionally abusive, calling me names, or being condescending, or embarring me in public. I don't know how much more i can take, but i also don't want to make the mistake of thinking that the gr is greener somewhere else.
