I think she has been rather rude/insensitive IMO, if she says something about your co-ordination/listening skills in future how about replying that you know you have an issue with this but you try your best? Maybe she really doesn't realise the challenges you have, and perhaps she is poor at empathy.

As for the lack of competition in the co-ed league, I personally as a woman would not have taken that as an insult, I don't see why being less competitive is a negative thing. I am in a mixed sports group and have to say it's my experience that generally women are less competitive, I personally prefer to train with other women for this very reason. That she sees this as an insult IMO says more about her than you.

I would just keep calm and point out if she says anything else bluntly/rudely about your challenges.
