How long would you hold a grudge (LONG but please respond :) ADVISE!!)?

okay, I am very confused by this story. But from what I can understand and in my opinion she is being reasonable when she says she is disappointed, because you are basically her mom and she wanted you to be there. However, I don't think she should be mad or anything like that because of everything you have given her in her life, and everything you have helped her with. She should appreciate it.
