||Thank you so much, CYA and YA and reader, for your responses. You've all given me such good advice and wise words.
CYA -- I respect Rabbi very much, still. I'm going to work to re-earn his trust, not only for my daughter's and his daughter's sake (as they are best friends), but for mine, as well.
YA -- Maybe some day Rabbi will apologize for acting out his anger, but you know, I won't wait for that. It was a tough day, and I hope he would forgive me if I did the same thing in a similar situation.
Reader -- Oh my, I know my critical mistake was giving the gifts to the kids without passing them through their Dad, first. Something I will never, ever, do again. It was due to ignorance, though, not with bad intentions. I adore his kids, and would never hurt them. So, I hope he can forgive me for being loving, yet ignorant.
Again, thank you for the help!
