May, I'm so sorry you had a bad time at gs' Communion. That priest sounds old-fashioned and cruel. Also, it was rude, imo, for the family to talk about getting together at the mgps right in front of you and not invite you. (((Hugs)))
This might be part of the problem:
"I once gave a book when they were little called "my 2 religions" and learned later by my other son, it was thrown out under some excuse."
My guess is that the children are being brought up to believe they are part of one religion only, no matter what their father's foo (family of origin) is. Their rigidity is old-fashioned, imo, but there are still some families like that. If they got the impression that you would try to interfere with that, it might have made them uncomfortable with you.
Maybe I shouldn't say "rigidity" since they do let the kids share Hanukkah and Passover with you IN YOUR HOME. (Do ds and dil come too?) But they may want only Catholicism to be IN THEIR HOME and part of the children's daily lives. You may not see it that way, but that is their choice as parents. (Even if ds is just going along with it, that's his choice too.) For your own peace of mind, please let go of the idea of your gc learning about their 2 heritages equally. That's probably not going to happen unless they choose to learn more about Judaism as they get older.
As for where your replies come out, it's at the end of the last page of the thread unless someone else posts after you. Your posts will have a green background.
