Is it any comfort to think that it was almost certainly harder on you than it was on your daughter? Both of my kids clung and cried like that when I left them with family or the childminder, and they were always fine 5 minutes afterwards. She loves spending time with you, she loves spending time with her daddy, and yes, in that moment she didn't want to let go of you - but she's only three. She'll have been okay. She probably doesn't remember you all living together. I know that's hard, but it's probably better to separate your own feelings from hers in that situation. Anger and grief and sadness is okay. And loving detachment will come and go.
