First things first, and I think your relationship with your daughter is first here, over any money thing. When the time is right you and she need your relationship back in some way, shape or form. The money thing is important, of course, and it would make any of us ANGRY, but even more angry that she is not returning your calls. Did she do this for a reaction from you? Did she get the reaction she wanted? Stop the card.....
Don't let your anger take over the relationship. Would it work to go find her unexpectedly and talk? Bottom line, she is your daughter AND you are her Mom. Lots of closeness it sounds prior to this recent move?
