Hello Maria: I noticed this is your first post here on PC. So... welcome to PsychCentral!

I hope you find the website to be of benefit.
I'm sorry you are struggling with all of these difficult issues.

I'm certainly no expert with regard to any of this.

But from what you wrote it sounds to me as though what you have asked for in the past, & how you are protecting your daughter's right to privacy in the present, are completely appropriate... &, at least from my perspective, the normal & natural way things ought to be handled. So I want to commend you for your determination to keep circumstances moving down the correct track, so to speak. Well done...
You mentioned having learned, last year, that your husband has led a double life throughout your marriage & that you don't know how to cope with everything.

Here are links to 4 articles, from PsychCentral's archives, on the topic of what to do when life falls apart. Hopefully some of the suggestions in these articles will be of some help:
