Am I a bitch?

I just had my first baby 4 weeks ago, this is my bfs family’s first grandchild and also nephew to his sister. Since the day I gave birth his mom has been blowing up my phone non stop, I understand she is excited, but I want to be left alone. I swear everyday for the past few weeks I have gotten a text message from her saying how she misses him or her sending me pictures that I’ve posted of him. She is literally driving me fucking insane, and if I don’t respond to every single message or comment she makes on my social media posts she gets butt hurt and tries to mention it to my bf. I want to tell my bf to kinda hint it to her to stop with all the messages, but I don’t want him to feel some type of way and I also don’t want to hurt her feelings.

(I also have a ton of secret anger and hatred towards his mom & sister bc of past issues and how they treat him so I’m sure this is what’s making the messages 1000x more annoying)
