Why won't my former boss leave me alone?

So i left my team finally (it was apit of snakes but somehow they all deserve each other) what sucks is my former boss is blocking my growth within the Co, i haven't told anyone he used to oppress me while in personal meetings and intentionally stare at my breasts ( he was a total jerk ) but why make it hard for me if i haven't told anyone. Why won't he just leave me alone, i went for 2 interviews and had bad references from what they said. I just want to forget this last one year with him and grow within the company but he has made it so hard..
