She didn't earn it

I was perfectly prepared for no boy to be good enough for my little girl. I mean, that's still a good 10 years away (I hope), but I was prepared nonetheless. The one that blindsided me? Emily's new mom. She announced right after Christmas that Crystal is her other mommy - she has two. I held up okay for about a week, but now the thought brings tears to my eyes. Emily is the only person in the world who gets to call me mommy. And now I have to share it with some 22-year old who lives with my ex-husband. She seems nice enough and she seems to have a good relationship with Emily, but I still don't think that qualifies her to be "Mommy." She just...didn't earn it.
