Time for her to pick up the parental duties. Split everything 50% if you're planning on sharing in the future, otherwise make sure you take care of it while leaving plenty of ME time. Time for your own mini-QLC (Quality Life Change). Arrange a babysitter, I know they're tough to find here in Sweden but they are around. Don't be so available her. You are, from this moment on, no longer at her beck and call. If it fits your schedule, fine, if not...she's SOL.
