I agree she is so young it will just be normal for her that dad has his place and mom has her place. My boys are 7 and 4 and so far they are taking it pretty well. My sitch isn't as complex as yours but I am taking the high road as far as the kids go. I have said nothing bad about their dad in front of them. We told them we weren't best friends anymore and needed some time apart. My boys ask questions but it hasn't been as bad as I thought it would be for now.
All you can do is be there for your D and be the best Dad you can be. At the end of the day she is the most important person. But to be the best Dad you can you need to be happy so work on you and focus on D. We are all here for you to vent.
