I guess not, but you're still her Mother. She doesn't know how lucky she is that you're still alive and that you, though you haven't technically given birth to her yet, love her. Enough to risk getting on her bad side by not liking her choice in boyfriends.
I can only wish that I had someone to stick up for me the way she has you. I can only imagine what my Mother would have said to her. I can only make wild guesses, because I barely remember her.
