Hi erfra - no you did nothing wrong - but it's a very difficult situation when you have feelings for her, and she for you, and she's married.
Some things you need to walk away from.
I agree with Bim that talking with her may not be a good thing for either of you right now, even if in some way it makes you feel better.
That kind of complication was what my life was all about when I was drinking.
I want better than that now - and so should you
