My husband lacks common sense and respect

I've come to my wits end with my husband. His actions are beyond unjustified. Let me give you a glimpse of what I deal with almost on a daily basis. It started off this evening when he begins questioning where I was this morning. I told him last week I joined a class called "transition to parenting" and it's every Tuesday from 10-12 for 12 weeks. We share a car and i informed him that they can send a taxi, at no cost to me to pick me up from my house. It's part of the great system of Ontario. So when he gets home this evening he's asking me where and why I didn't tell him yesterday, he's searching online about the centre. So I give him their schedule that they gave me for the month of December, but the times don't match the times that I attended. So the questioning increases. At this point I'm fed up with the lack of trust and the fact that our son was crying so he decided to just get him and take him out of his room at 11pm. When he should have just soothed him back to sleep. He starts to manhandle me and grab my arms with force and not let me go. Then finally when he does he sticks his dick out in my face. I just began crying hysterically cause I felt like a piece of garbage, not his wife. Then he tries telling me to calm down and that he was "kidding". Then he makes me swear on my dead sisters body that I was at the class the time I said. The fact that he gets my sister involved when she just died 6 mths ago is hurtful. I need some advice, how do I handle a man like this? I'm just sad and have had enough.
