Imperfect neighbor

I was out of town when Natacha told me about our new flatmate. Muscular, handsome and reserved, he never talks to anyone. So far, we haven't met. And I'm not interested at all. I never thought I'd see Bill Simmons again, the man who destroyed me in the past. In fact, this new roommate is none other than my new boss and also the father of my daughter. Now that he's back, I won't let him walk all over me.
I've suffered enough as it is. Besides, he doesn't know about my daughter. And he never will. That's much better. I want to avoid him at all costs, but how can I do that when he is now in my life everywhere?
