My MIL and SIL named a baby after my late daughter behind my back, then blew up at me for being upset

Very very very long day! The war with my mil & "sil" (little brother in laws baby mama/gf) jumped on me again today with a bunch of evil texts all because my mil tried texting me today saying she "loved me" after picking sides with the "sil" on Friday about the girl naming her child after my deceased daughter behind my back. And then talking bad about me for the past 4 days with the girl saying I was dumb for being mad......well when she said she loved me I couldn't help but ask...."then why have you done this to me and abandoned me when I was needing you most! and why were you sharing all my private feelings that I trusted to share with you with the girl that already don't like me...thats wrong." and then next thing I know my mil done shared THAT whole conversation with the girl AGAIN! And next thing ik they were both texting me cussing me out AGAIN! Soo I said "see what I mean why do you do that, just loose my number!" So now they are both kicked out my life since she wants to pick sides and jump on me all the time.
