Sounds like a successful co-parenting session. You got your time in the middle of the 10-day stretches, and most issues the MC said were hers to deal with in IC--"Expectations are reservations for future resentments." Since she cancelled her IC sessions, I suppose she feels no urgency in resolving those.
Was there any discussion about your reporting your whereabouts during custody?
I agree her fear of you, even if completely unwarranted, opens you up to craziness during the divorce. As you say, not much you can do about that except to be a great dad and then deal with it if/when it happens.
