Good job Chris. I remember early on, about a month after my W moved out it was birthday and my W asked if I wanted her to be there and I told her "no", that I just wanted to spend it with the girls. It was hard as h$ll to tell her but I felt much better after I made the decision. I also think you made the right call.
Sorry about your G-Ma! Mine died about 8 years ago, I was her favorite and she was mine. My youngest was about 6 months old when she died and unfortunately they never got to meet. It is something I will regret for the rest of my life.
