There's no reason to be in a relationship with a man that believes his lies to you don't count specifically because you're a Christian, and he's Muslim. There's no reason to even be FWB's with a Muslim man because he believes you're just a placeholder until they find a virgin to marry. There's no reason to be in a relationship with a man who would rather kill you than allow you to break up with him.

I could go on. But, there's no reason.
