Scared to date again

I met this guy who is very sweet to me and wants to pursue a relationship with me. However I’m so scared because I’ve been left for other people in my past relationships and I was cheated on. He was honest with me and told me that he cheated on a girlfriend of his back then by talking to other women behind her back, but he said that he’s different now. I really don’t know what to do. I like him, but I’m scared that I’m going to get hurt.
