<human>: Provide a brief overview of the text.

Alright so 2 years ago, I cut it off with my then girlfriend of 3 years.  Things were very rocky near the end and we were finding ourselves getting in more fights and the whole things didn't end up the best that it could have.  No punches or anything remotely near that were thrown and everything was mainly done over the phone because we became to despise even looking at the other.

Alright.

So 2 years pass and I'm thinking nothing of it.  I start talking to my friend, whose sister is friends with my ex, and he tells me that my ex girlfriend has been telling his sister and her other friends that I was physically and emotionally abusive.  I'm like wtf? and originally I don't really care because my true friends know who I am and near the end, my ex girlfriends was showing that she was pretty manipulative with me and her friends so I just thought that she was continuing with her old ways. Then a couple months, I drive by a kid who I don't recognize, after I look back at him, he is flicking me off.  I realize that he is my ex's now boyfriend.  I still don't understand why he is flicking me off after I have done nothing to him, never had said a word to him, and never had anything to do with his girlfriend for over 2 years.  I am now suspecting that she is spreading and lying to everyone that I am physically and emotionally abusive.

What do I do?
<bot>: Ex girlfriend is telling her friends and maybe her boyfriend, that I physically abused her while dating 2 years ago.  These are obvious lies.
