SNOWS.
You're going to drive yourself crazy if you examine each decision you had to make on your own, to make sure the three of you were taken care of and could survive in a world without magic. Hindsight gives you all sorts of perspectives after the fact, but the decisions you made kept them happy back home, right? I can't let you blame yourself for what worked before.
Things change, situations change, and that's what's happening here. We have to adapt to what's happening and not feel bad about what used to be right before.
This August isn't your son. The other one was and I'm sure he was a brother to Emma, but this one never was and things will be different because of that.
