My Mother In Law The Drama seeking Princess

Well my new years was ruined today by my mother in law since this morning decidee to ignore me after i tried speaking to her twice and deciding to think okay i wont bother speaking with you then as im not seven even tho i can probally see my reaction to what she was doing childish. So the night progresses and she decideds to address everyone saying she doesnt like screamers when people are in labour and screamers would get a slap from her ( yes if your reading it shes that bold in what she says ) so after being scared for months as this is my first child about going in to labour i finally decided enoughs enough give her a dirty look and walked out of the room which she then told me i only did such thing because i had a audience, no because im not going to sit there and listen to someone trying to scare me like that. She doesnt seem to ask anyone how they are and let alone me and always moans about how crap her life is. Tonight was the last draw of her getting her say in everything little thing. She drinks a lot and doesnt speak to her two sons due to her being a idiot and now i honestly am on the verge of not speaking to her myself. We are trying our hardest to find our own place and its putting a strain on me and my partners relationship due to having to live with her for the time being. I dont appietate her calling me a bitch and its now scaring me that she feela the need to tell me when she will watch my child when i should be the one telling her it makes me feel like shes trying to take him from me in a way am i being a idiot or is she trying to just start something. As my boyfriend offered my mom to be in the labour room with me which i dont mind as he thought a girl will need her mom at that time and id be more comfty with her being there carming me down and the mother in law decided to say tonight drunk that thats the reason why you dont want me jn the labour room as if you scream id slap you when im not being funny i dont want someone there making me feel worse instead of supporting me she tells me how hard it is and trying to scare me every step until i had enough tonight which she then called me a bitch for. Like honestly shes head fucking me x
