I'm totally in tears
Sometimes we just know what we need. If you feel a bond with this little girl then keep her. Just explain to him that you can't explain but you know in your heart it's the right thing to do.
My Husband and I have this sort of relationship.
He digs his heels in but when he knows I am truly serious and I will not be swayed and my heart is leading me ,not my emotions (and it has only happened twice in our marriage, and it wasn't pet related) he lets go of the control.
Grieving is a process. Only time will heal you.
Your post really got to my heart and I wish you the very best.
