The (very) high road. I've told this story elsewhere here, so you might be getting a second dose.
Daughter decided to quit. We already had at least one team lined up for next year. She was injured and when she got better, they didn't return her to the lineup even in showcases. Furthermore, they NEVER spoke to her about it. So we decided to quit on a Friday after two tournament games. But it turned out our squad of 15 girls would be cut to 12 the following day because three girls would be out for the ACT.
So my daughter came to me and said "Dad - I think we should wait until tomorrow, because they'll only have 11 players if I quit today." I praised my daughter for that very mature decision and that's what we did. The following game, my daughter sat the first game and played a tiny bit in the second game before she was taken out when the ACT girls showed up. Here is the entirety of my "talk" with the coaches:
I asked my daughter if she had anything to add, and she said "I love this team" and I got chocked up. The coaches said something about "wishing you the best" and "I hope you get the playing time you want" but I didn't really listen. The whole conversation start to finish took about 30 seconds
