CTH, Just ask her. Manage you anxiety and ask her.
Make sure its about you and your decisions and nothing else. This is the hard part.
Try something like I've decided after being apart for the last eight months that this agreement is not working for me (or the kids). I would like to change it so one I have the kids 50% of the time. Additionally I plan on reducing my support payments accordingly.
It would help if you had a plan in mind or on paper for how you plan to split custody 50/50.
