Thank you all for your kindness and concern.
It's hard to know what is right when one day he's really nice and caring the next he's cold and aloof and then he's drinking and mean. I have figured out that when he wants me to get over being mad he will buy me something that he knows will make me happy. Little does he know that all I want is normal and quiet, not things.
Someone asked if I could get a job away from his family, I could with a lot of questions and harassment. My daughter is starting medical school in less than a month so I will need that salary for right now. Ugh, it's all a giant mess. I don't know what to say...
