, this was NOT a decision I made lightly/spur of the moment,
They never are. You have to do what is right for her and you know that better than anyone.
Maybe as young children there are no conditions on love. ( but my 13 year old is pretty much done with her father)
They (we) eventually grow up (quickly) and see parents for who they are and how they treated us.
She may not feel it now, but the things her mom does now will impact her future feelings. She will remember and not fondly.
That's where you come in - Dad will pick up all the slack and make everything ok.
Cause that is what we do.
