She didn't want to talk to you about the papers because she wants to avoid all conflict with you at this point. Same reason she is avoiding you in general. She only has 60 minutes per week of "empathy face" and she has to save it up for MC.
She probably realized that the note might piss you off a little, but that was a small risk compared to taking the chance that handing you the papers would set off an argument. Which might send you straight to your lawyer.
Glad you are seeing the lawyer tomorrow. Remember that whatever legal agreement you come to, it should be the fallback position that is enforceable if (when) you two end up hating each other's guts. You are free to do any actual schedule you two can agree on, as long as you are getting along.
One last point: Don't assume your W only will work the hours she is now. Again, think 3 years or 15 years from now. Any CS you agree to should be based on her 40-hour/week earning potential and 50/50 parenting.
