Hey - I read the long one mulling it over still, but wanted you to know I read it.
Hold fast to your custody. Whatever you do now is precedent setting, so if you don't change it and the baby does well, I think you're ok. I wish you had the emails still, but I wish more that you won't end up needing them
I just worry about you getting used - she moved out and dealing with no support at 2 am is how single motherhood works. But, do what's working, right? Cheese in the tunnel and all that.
If she pushes on child expert, you have a good comparison to reason with her - "look, you felt like those emails were a way I could take the baby from you. I feel like this child expert is a way you could take the baby from me. I'm sure that's not your intention, since we agreed that having time split like this is in his best interests since he will know his parents this way"
Frankly, once you are past breast feeding, which you are, I think you have a pretty good set up. The baby is too young to be confused about this and not old enough to have friend/school/room weirdness with the back and forth.
Faith is, at one and the same time, absolutely necessary and altogether impossible. --Stanislaw Lem
