I dated a guy like this. I knew he saw other women, he would actually leave me to go on a date with someone else and come back to me after that date was over. I hated myself for allowing this to happen but the moments we were together kept giving me hope for the future. In reality my ex was emotionally abusing me. He knew that I could not say no to him and he used me for sex when he couldn't get it elsewhere. He did not care about me at all. It was hard to completely end things and it really wasn't until meeting my husband that I was able to put this jerk behind me.
