My [25m] gf [24f] of 6 months thinks I slept with her friend before we met - I didn't

I've been dating my gf, L, whom I met on Tinder, for about half a year. Things have honestly been pretty great up until now, we've talked about what we want in life and we could both see ourselves moving in together in the not-so-distant future. We've had some small bumps in the road like everyone has but I feel like we've dealt with them in a mature way.

A couple days ago we went to a social event with a group of her friends. I've met these people a few times but only briefly and I noticed there was some giggling and exchanged looks between them through the evening. I didn't think anything of it since I don't know these people and I don't know how they normally act. Later when we got back to my place we're talking about the evening and L suddenly stops me and says "Name... I know why you and A are so weird around each other, and it's not a big deal to me". A is one of her best friends. I have no idea what she's talking about so I tell her. She rolls her eyes and tries to change the subject but I keep pushing for an answer and she tells me she knows I hooked up with A several times, and that her friends think it's really funny that I'm pretending like I don't know her.

Now, there is absolutely no chance that I ever slept with this person, I have never met her before. I did use Tinder but I'm not the kind of person who goes on there to find a new hookup every weekend or something. I only met up with a couple girls from there before L, they weren't very good dates and I didn't sleep with them. I've slept with five girls my entire life so it's not hard to keep track. I don't judge anyone for how many people they sleep with but I just have no interest in sleeping with strangers.

Apparently way back when we started chatting on Tinder L showed my profile to her friends and A said we used to hook up. I deny it and she gets more annoyed saying she doesn't get why it's such a big deal to admit. We go to sleep and she leaves early in the morning for work. We text later and she makes a snide remark about honesty so I tell her either her friend is mistaken (which I doubt cause I have a pretty unusual name) or lying. I tell her honestly I think A just made it up on the spot just to say something interesting, and then it backfired when we started dating seriously. Instead of admitting she made it up she doubled down on it.

Big mistake, L blows up telling me it was so obvious I was uncomfortable being in a room with the two of them (??), how she's disappointed that I'm making this into a thing and how I'm trying to gaslight and manipulate her (???) into thinking her best friend is a liar.

This was yesterday and we haven't spoken a word since. I just have no idea what to say. I'm upset about being called a liar but I'm more upset that things were going so well and we had a big argument over this stupid thing. Wtf do I do?

TL;DR

Gf is mad that I can't admit to hooking up with her friend in the past, whom I have never seen before and definitely never slept with. Now I'm the bad guy for calling this friend a liar.
