Someone please help. I want to pull my hair out.

My boyfriends mom has not texted and asked about any of my baby doctor appointments, she talks about me behind my back to her other daughter in laws, (she talks about them also behind their backs) and constantly wants to tell my boyfriend everything that is going on in his ex girlfriends live, to me that is disrespectful. His aunt is the same way. Am I wrong to not want my baby to be around these people when she gets here? I'm a young first time mother at 19 and I'm trying to handle this situation in the most mature way possible, I just need some advice. I feel like if those people weren't concerned about the babies health while I've had a hard pregnancy why be concerned and involved when she's here. Also my boyfriends mom lives with her other son and daughter in law that had a baby, and he's a year old now. He goes to all of his doctor appointments and etc, and is all about him. But hasn't been one bit involved or concerned with her granddaughter.  Every health issue I have had, like passing out randomly in stores and etc, vomiting, anemia, low amniotic fluid, she never has been concerned about. She just tells my boyfriend that I'm exaggerating that she didn't experience any of this. What should I do? I've tried talking to him about his mom, his aunt and his sisterinlaw all being two faced, and he just says I'm bitching. Meanwhile we also have his older brother, his 18 year old girlfriend and another one of his friends living in our two bedroom house. I have to cook and clean after 5 and I don't think it's fair. He is my resonsibility but others aren't. For example I will mop and sweep the floors and they all walk in with their shoes on, I fix dinner and they won't even put their plates in the sink they sit in on the kitchen table and won't even scrap the plates off in the trash. I'm fed up. Someone please help me.
