Do you think it was weird that I cried?

My ex and I recently started dating again. He's cheated on me in the past and he flirted with another girl recently on Facebook. While we were having sex today he was on top of me and I started thinking about him hurting me again and started to cry. He stopped for a few minutes and asked what's wrong and I told him that I didn't want to be hurt again.
I want the truth. I'm very emotional and I hate that about myself. I really didn't want to cry but all I could think about was the last time we had sex and he texted a girl the next day on Facebook saying he wanted to have sex with her. That really hurt and was recent and I took him back again after doing that.
