Hello, I write here asking for advice.

About the middle of 2014 I started dating a girl we will call "L". I am a young guy, being only 18 at the time where I started dating her. We were old friends from high school although the relationship didn't last long, only two months. We never argued or fought until the night I dumped her. Here are the basics of what happened that night.

She was hosting a party where she got very drunk and started feeling up other guys. I tried talking with her asking what she was doing, things escalated and she moved away. In a upset tone I raised my voice and asked "Why are you doing this?". I managed to quietly talk to her later on although not much got through as she was in a very intoxicated state. Soon after she continued to feel up other men and refused to talk to me. She told me, to leave her be and if I don't trust her we should break up. Saying I didn't want that she began to walk away. That's when I raised my voice the second and last time saying "I'm dumping you, you bitch". Followed by me walking off to my car getting ready to drive off (I didn't have anything to drink that night). When two good mates stopped me from driving off in a upset state. One stayed with me and we listen to the "bohemian rhapsody" if i recall correctly. Shortly after police turn up and approach my car. Asking if that house was hosting the party and for me to wait here while they checked it out. Turns out the police had come on an account of a potential domestic violence situation, after checking the house and seeing no one was hurt and nothing was broken they talked to me and I explained that I was upset due to what she was doing and had raised my voice twice. They asked for my contact information and let me go. (Were actually very nice detectives, I was very grateful they saw my side of the story). Later on in the night I texted her saying goodnight and we discussed that in the morning we will talk about what happened. (I forgot to mention throughout the entire night she yelled/ raised her voice at least half the time she spoke to me, just as a comparison of my twice)

The next morning we text and she explains that she did something bad after we texted last night. I drive to hers and she tells me that she made out with someone in her bed after we texted. As I had technically broken up with her the night before )even though she didn't remember) I didn't care. We talk and we break up, I tell her she wont see me again and leave.

A few months later i get a text from a old close friend saying that "L" is telling people I hit her while we dated. This starts to come up with other friends and such. Then last night at a party, a close friend explains that she appartenly has been telling people that i have been calling her and harassing her. (I NEVER hit her, I've never hit anyone! I also have had her number deleted since the morning I broke up with her).

It has come to the point where it has come up enough I wish to do something about it and crease these harmful and damaging accusations. I ask you what I should do once I have evidence supporting that she is making false accusations and harming my reputation and image.

Thank you for your time to read this :)

TLDR: Ex Girlfriend making false claims that I assaulted her and virtually stalked her. I seek advice :(
