Normally I would probably not giving a flying shit

But my situation is a bit different. I gave birth to my daughter at 22 weeks on 3-3-2011, we had a burial and my SIL & BIL and friends and close family.
I was 40 at the time with 3 boys 20, 17 and 12 and this baby was soooooooooo unexpected and such a blessing at my age I felt, finally got my girl

My SIL also had 3 boys and said she wanted no more, but miraculously she got pregnant 8 weeks later, "It was an accident" her boys were also older 17, 14 and 10.. Well she had her girl and the whole nine months would not say what she was having fair enough, but I knew it was a girl by the way she was carrying, I am Godmother to her oldest so i have seen how she has carried her 3 pregnancies before that. The WHOLE 9 months never mentions a name . at 6 months I asked her again no names yet? She was like oh I don't know my husband likes Mia.. So she gives birth and names her my baby MY baby's name that passed away

never asked , never mentioned, never asked how would we feel about it> So we have not talked in a year I refuse to ever see her again, cause if I do I would probably beat the ever loving shit out of her.
She literally broke my heart showed us NO respect and thinks what she did was perfectly fine, so yea in my case it was a big deal-and it was stealing in my eyes. The whole family is broken apart cause of what she did and she thinks I would forgive this and be around a newborn with my daughter's name? The only word I have for her is cruel, Thank You
