Emotional Abuse?

My husband has become a jerk over the last six months. He started school in August and certain things I have blown off because I attributed them to "stress". He has become a jerk because he wakes up in a bad mood yells at the kids and expects them not to cry and for me not to be mad. This whole month it just has become worse. I feel the tension and distance. Yesterday was horrible he began picking on a show I was watching because I would not change the channel and then from there he started picking on my family. I called him a jerk and I threw the remote on the sofa and threw my cup of water on the floor in the kitchen because I was sooo mad that I was not allowed to relax after a long day at work. And he knows what will make me mad. It always seems to me that when he has a "bad day" all of us do and it is not fair and I don't think it is NOT right. Would this be emotinal abuse? We always argue over the same issues and issues that i thought were "dead" because I make an effort not to bring them up, he brings up continously. I am considering a separation.
