Don't take it personally. You are really the full-time parent and dad is more like the vacation parent. Men also tend to be more hands-off in general. So unfortunately, you might tend to be the one who gets more rebellion from her. That's fairly normal in a situation like yours.
Hey, I'm not divorced, but I've been the main one to deal with my kids their whole lives since I've been the one at home with them, relating to them, disciplining them, pushing them, etc., so dad often seems like a lot more fun to my kids than I do. I don't take it personally - I don't care - I know I'm the better parent.
And I PROMISE you - keep loving her and listening to her, and even if you are the less "fun" parent, she will NOT love you less. You will absolutely not lose her love by giving her boundaries.
Rae W., below, put it very nicely.
