How do I tell her???

Yazmin
So as I have posted my husband and I are no longer together. I have a daughter (not his) and she adores him. We separated once before and it devasted her so much to the point where she asked me "why does everyone I love leave me?" How can I possibly tell her that we're done for good? I know in a way this is all my fault because I put us in that situation again but I honestly thought he changed and cared. How do you tell a 9 year old that one of the people she loves most is no longer going to be around?...
