I just dance. I don't think dancing has anything to do with wihether or not someone is partnered.

hmmm ok , well this is happening a lot and when asked about the partner the answer is "she's not online lots anymore so it's not an issue"

Dancing is just dancing. It's not (necessarily) flirting, and it's rarely cheating. I went dancing all the time (still do sometimes), and SquirtN never went with. I just danced with whoever was available.
