Scott, what I will tell you is that whatever you decide with Easter, or coparenting, or mediation, etc, do it WITHOUT expectations! I am still seeing a bit of a tendency to have expectations.
Take the Easter plan. IF you can go there, stay the night, spend Easter around her and with the kids......WITHOUT EXPECTATIONS, then do it. IF you cannot then tell her you are out.
That is your goal...no expectations. And if you can't do something that is voluntary without them, then don't do it. There will come a time when you can do things with her and the kids without those expectations, but be honest with yourself about where you are in relation to expectations.
