Yes, I think so Dingedheart (I just can't write DH cause to my mind that's dear husband-sorry).
It's rough on kids when their parents are lying.
As the one who was lying-I feel safe in saying, it's just fucked up to do that to your kids.
My oldest figured out I was having an affair, she's not Maca's child. It impacted her relationship with him, because whether or not she thought it was wrong of me, I'm mom and she knew if we split-she would go with me. So she didn't want to open up and get close to him, because in her mind, he was already GOING to "abandon" her-cause of what I was doing.
I feel for your daughter. It's so easy to see what's going on around you at that age, kids really aren't as naive as people like to believe.
