I am not sure exactly what made it change for me. I was really cold in the beginning couldn't even look at him. Then of course treated him like the mailman. Now it is like talking to the guy I knew.
I still see how things hurt my kids, how he still hurts them now. So I know that he is still in a fog.
So something changed in me. I figured I needed to coparent to some degree with him. I melted a bit. The kids are a bit more at ease with him as well. So I think you are on to something by being kinder. As your relationship thaws between the two of you, it may also warm between you and your daughter. 16 is a hard age. I have one myself.
