I've been frequenting the gym numerous times a week, now, and I've paid attention to some of the people and how they interact. Women who come in without headphones and are barely breaking a sweat tend to be on the lookout for men. Men, it's much harder to tell for me. The main thing I've noticed is that men tend to flaunt their body and kind of hang around the girls. Every time I go, I have men trying to interact with me when I have headphones on. It's always something. Either being followed or interrupted when I'm clearly busy. She may be annoyed because of frequent attention by other men. I think only interact when she is not busy. Say, if she's getting ready to leave or if she's taking a short break. When you're in the middle of something, it can be irritating and frustrating to have people pestering you. I wouldn't take it personally. I hope what I said helps. People can be pretty confusing and difficult for us Aspies to read.
