I did it, I told DD about her biological father

[Cocolove]

I dont understand my own feelings, I cant imagine what she feels

[Catastrophic]

You did the right thing xox you made the choice and you know deep down in your heart it is the right one, she had a right to know... (I didn't catch her age, how old is she?) tears are too be expected, these are not bad tears, showing emotion is not a bad thing. When she wakes up in the morning give her the biggest cuddle and just keep being open and honest with her.
xoxox a huge hugs to you and to her xoxox
