What to think if my ex mentions how her rebound had a tiny dick?

She also mentioned some otherstuff about how he was obsessed and insecure about me. With stalking my social media, accusing her of still loving me. And vented a lot about how he was shit to her and borderline abusive. Granted she legitimately did it to work through stuff.

But one other thing stood out about what she was saying. Something that she definitely didn't have to mention. Her words were effectively this.

"When we would have sex, I never thought about him. I always thought about other stuff **Pauses** and other people" (Obviously referencing me)
