I got a text from his ex - TF do I do now?

Just now I woke up and saw a text from a strange number. Back story: I live in a small town and started dating a man who’s going through a divorce. Word travels fast and I was kind of mad that he wouldn’t tell his ex, especially because she had confronted him about it (someone saw us out and told her). Well, I guess that changed because this is what I woke up to:

“A pandemic. What a strange time to be going through a divorce. I did get a confession out of him tonight. I knew it. Like everyone else. U act like u don't know why I told u not to speak to me but bitch you know. You could have had a friend but instead u got fucked. I saw u coming a mile away. Typical. I've met you at least a dozen times. You're not special!”

I mean bitch TF? They’re not together anymore. Idk what the fuck she wants from me. We weren’t friends and we were never going to be friends. We were acquaintances from living in the same small town.

This is a lot of fucking drama and I do not need it. Do I respond? Do I tell him?
