Discuss n's answer to: Am I unreasonable to ask for help around the house?

If you know in your heart that this marriage cannot be rescued through therapy, then take matters into your own hands and see an attorney for some real help in getting out of this predicament. 

    You will never regret taking hold of the situation and making a positive decision.  He doesn't sound like worth staying with.  If he has the disposition you describe, then he doesn't care one whit about you.  Like Shuddupandkissme said, your health will suffer if you stay.  Do yourself a favor and make some real plans for leaving this situation. 

    Best of luck and much love to you.  Courage is a beautiful thing to have....get some...
