Also, you may want to think about cutting back on face timing for now. Or figuring out how to do it without needing to speak with your W during it. It doesn't sound like its good for you to be seeing so much of her. Also, you could use a little mystery; always being at home alone at 730 (or whatever time it is) doesn't give you much chance to go do something and it lets W know exactly what you're doing all night.

With 50% custody, I think it's ok to go a night or two without talking to S...especially at this age, I'm sure he isn't that good at face timing. Hell, I have a 6 year old that can't do it Cormier than a couple minutes before the kid is off doing something else...
