There you go! He's coming around, Ioavva. This trust in you re mothering seems like a big issue in your sitch, especially after the custody battle.
IMHO, I'd focus solely on this for the day, working to relaxed and in the moment with the kids, and leave the R convo for another time. In fact, Ioavva you might wait 2-3 days to do so, letting your mood shift and your successful interactions with the kids today (I predict so!) to sink into you, the kids, and indirectly, H. My intuition tells me this is not the time for an R talk (after a stressful day over the weekend/growing doubts and tension about R/are you still mid-period -therefore hormones may affect your ability to be at your top game as-ifing, etc...), but you know your sitch best.
Too much ridigity is never a good thing, so H becoming more so regarding vegetarianism is a red flag for me. Yet, his asking you to watch the kids is a nice way of testing the waters.
You will win part of H's heart and confidence via your Rs with the children, Ioavva. Regardless of H, they need and deserve you in their lives. Not sure if this is his view, but a mother or father never 'babysits' their own children. They are your children, too, and you and they deserve each other very much. I truly hope you can enjoy each other today!
