She wants to move 2 hours away

Just got the text that she's looking at jobs and places further out. Our current agreement is we both stay within the school district. I don't want to be that guy but if she moves that basically kills my time with the kids on weekdays. Should I be proactive about this legally or try to talk to her first? My lawyer friend said I need to address it NOW not later. Feeling really anxious about losing time with them.
