We actually discussed this in my Racism and Sexism class at school this week. This sort of comes from a feminist outlook (not mine), but my professor is a hardcore feminist and this is what she said. That men want authority over women. Looking at society it is clear that although men and women are closer to equality than ever before men are still viewed higher than women. They hold the most power in the government, they are the providers, the protectors, etc. Men do not realize it, but they are privileged when it comes to control. They are viewed as stronger, so it is easy for them to get away with controlling women.
Jealousy is an issue in many relationships. Maybe this guy was jealous of your past relationships and he obviously wanted to make you feel bad about them. Sometimes it starts out great and gets bad because the guy sees that he can treat you that way. You know? Like if you don't stand up to him right away and let him get away with mistreating you he is going to think it is okay. Even if it isn't. Each time he might push a little more until it gets out of hand and you are put in a situation where you do not know what to do. You love him, but you don't love the way he treats you. But you didn't say anything about how he was treating you, so he thinks it is okay. He feels that he is entitled to harming you, to control you.
This could be wrong, but it's a thought.
