Hi STH, it's good to see your update despite it not being better news. My separation isn't formal either. Has your wife asked for a legal separation or divorce? I bet your son would love having you attend his school function. That's so sad you can only see him on weekends. Everything else about your 2019 sounds great but getting divorced is just such a sad outcome after your patience and willingness to compromise. You never know for sure what'll happen though. Your wife could always realize what she's about to lose, but it sounds like divorce would at least help to clarify some of these legal, financial, and custody issues that have been lingering.
