Boyfriends family

My boyfriends family has been driving me insane i cant take it anymore i say something to my boyfriend and he has something to say about what my parents do.

His mom sister and brothers girlfriend make me literally dislike them lately.

Mom - his mom commented on a post that my bf commented on and she made a comment like oh ur just jealous ur gf dont cook. Its like are u kidding me?! I dont cook? I cook the kids meals 4 xs a day my self food i clean the hole house by myself i take care of the dog by myself. I do everything else but cook sometimes.

his sister - a pic of this dog i was gonna get and she comes back with isnt one enough coming from someone who has 2 cats and a bunny ans a dog and lives with her mother in law i have my own house.

Brothers gf - everything i say post get or do she tries to out do me or Copies me. I bought my son 4 outfits she got the same ones , i post my sons god mom all a sudden she has one , i post where im registered she makes the same registries , i post my stroller ane carseat she commented oh mine does the same thing and i only payed x amount i show my bf the tattoo i want she goes omg i was gonna get the same one.

Its just so annoying im so over it its like someone always has to say something its like i raise and take care of there other grandchildren who arent mine and do everything i can to make sure everythings clean and set all while being 8 months pregnant
