Gosh, she sounds diabolical!
I am a cm and we do at least one craft activity (painting, sticking, etc) a week at home. We also go to groups where we do other arts and crafts.
Weather permitting, we try and go outside to the park or to feed the ducks every day to get fresh air.
Asking you for money all the time is not right. I, as yet, have never asked for extra money from my mindees to go on trips, although if it was an expensive trip, I would ask for a voluntary contribution.
I think you are better off finding a new cm as you are clearing not having a good experience with your one.
