Hi mates

Going through a divorce and my stbx is insisting on a 50-50 custody. Normally many men would be happy with this but I am a little anxious because I work three jobs and am super busy. The kids are under 10. She is doing it deliberately so she can have time to do her personal stuff and so she can disrupt my schedule. How does a 50-50 custody work? What have your experiences been? I love my kids and look forward to actually spending quality time with them but not sure how to balance with work which has a lot of international travel. Thanks in advance!
