Is it normal to still want to be an abusive person??

About two and a half months ago I broke up with my boyfriend/ my best friends step brother. We hadn't been together long about almost four months. And we had known each other since January of this year. I didn't like him right away, we were really close friends and I have liked his cousin. So he would help me out. Once we finally started dating, it was good but I noticed weird things about him.. Like he was very aggressive and when we were together in person, he was VERY protective. There were times when he was creepy~ he would want pictures (naked pictures) and he was "addicted" to porn and he just couldn't stop.. And then when we would do physical stuff, he would creepily ..smell his fingers afterward... And then after my best friend started to notice that he would hit me pretty badly, I would get bruises. Sometimes on my stomachs and arms. I noticed when he kicked me in the stomach, I love him. And I finally broke up with him but I still want him back, he is soo different know.. Is it normal to still want to be with him...???
