Whats A girl to do????

I think I have the worst marriage in the history of the world. I have had a migraine for 2 days now and my husband tells me to get off my LAZY BUTT and do something with my kids so he can take a nap? i'm not sure but when is this karma supposed to come back around>? He has started giving me a terrible time lately, and lets face it the only reason he is staying with me is because he thinks he won't have to work after i graduate from nursing school. Those in sickness and in health vows didn't mean anything though, and yes he DID know about the migraines before we got married. Ncan't believe one person could be so hateful. He is always complaining about the money my medicine costs. I am so tired of being married.
