Thanks - guess I'm in the market for a therapist, thenWell again there really isn't anything that will "resolve" the matter or correct the matter. She was not under any legal obligation to tell you about the child. Maybe she wasn't even sure. Maybe she was scared to tell you, maybe she thought you wouldn't want to know, I don't know. I get that you are angry and you want to punish the mother. You need to work that out in counseling. Going after the mother to punish her in some way could also backfire on you by further alienating the daughter.
