Has anyone dated a Palestinian immigrant before?

I am single mother, my son is 17 years old. We live in Frankfurt. At my work I meet a man, he is from Palestine, an immigrant. We get along good, because I was curious about the Palestine Israel conflict and his story about exodus, why he come to Germany. Now he is into dating me.
My son from beginning did not like him. Maybe because he is Muslim and not German. One night my new boyfriend was with me in my home. We were intimate and he was giving it hard in the a$$ which was painful and i was screaming but my voice muffled because of a cloth he put in my mouth. My son see us by accident and since then he behave strange when my boyfriend come to visit. I don’t know what I should do. Should i break up or what?
