Ex called me last night drunk

Me and my ex broke up after 11 months of going out in September. He texted me so drunk last night saying he wanted to come up to have sex. He ended up calling me and was literally begging and told me he loved me. I told him to go to sleep. This morning he text saying sorry but continued asking and said if I ever wanted just sex to call him. I lost my temper and told him I didn't like what he was saying, he hurt me and he can't just pop up and say all this and expect me to be okay with it. He said I was over reacting, I turned something so simple complicated and that it was "just sex". Did I over react? I still have feelings for him but I don't think he has the same type of feelings
