Edit: location is Texas

Never thought this would happen to me.

Some context here, I'm in a three person open polyamorous relationship with my wife and girlfriend, and we are all sluts with an open relationship. Friday night, a girl (a third girl, not the wife or the gf that live with me) that I had been with a few years back wanted to come over. We had been flirting pretty heavily at that point. The text conversation, which I have a copy of, is literally her asking what the plan was for the night, and my responding "steak and sex?", She says she feels kinda drained, and I said, oh ok, just steak and hang then? She says, no, she meant she's feeling social anxiety, but that she's fine for sex. My gf was previously going out, and it was just going to be the wife, me, and new girl. Her plans cancel and so it's an evening with all four of us. Generally, when there's that much, ah, imbalance between the girls and guys, I get kinda nervous and in my head about not being able to satisfy all of them and have a hard time performing. I explain this to new girl over text, that I'm feeling some social anxiety and most likely won't be able to have sex.

All of the above are in text and I have saved copies.

So she comes over, she's flirty, played some footsie with me, then we go outside, smoke a joint, we share a blanket at this time, because it's cold, and no touching occurs here, because I'm really in my head at this point after the initial flirting and know that sex isn't gonna happen. We chill for the rest of the evening, and she stays for maybe a total of 3-4 hours and we call it a night. I hug her good bye, and this is the most physical contact we had all night.

Next day, I find out that she's told our friend group that I had made her feel super uncomfortable with my inappropriate touching, causing much recriminations and fallout. I have the texts, even the bit where she admitted she initiated the footsies, but I don't know what I should do with it.

While I am an attorney, I'm more the contract drafting sort who's not really been inside of a courtroom, should I be worried? Do I need to sue her for defamation? I feel like I've been bullied and taken advantage of and have nowhere to go for justice.
