Sorry to hear that you are having trouble with your model.
Models are defiantely high maintance and for the most part they are very needy. Unfortunately if the model feels ackward and
uncomfortable she won't want to continue working with who ever that is making her feels that way.
Maybe you should consider writing up weekly or monthly contracts for your models so that they get cash at the end of each week like a normal job
but you withhold a portion until the end of the contract so that the model doesn't ditch on you as she wants the final payment.
Just a suggestion.

If you want her back you may want to butter her up.
Take her to lunch to discuss it and then maybe to a salon and spa for a pedicure or something. A little pampering can go a long way!
I wish you well and good luck with the model.
