**update***MY PARTNER WANTS HIS MOTHER IN THE ROOM!!!

Sarah
Sos !! 
Ok so here is a little run down. 
I have known my partner for 10 years although have not had much to do with each other until we re connected September last year when I came back to our home town for a holiday and everything just took off. Literally it was love at first site/second site. I moved straight into his mothers place instead of flying back to Ayres rock for work. He has a child to another woman (had her at 19 we are now 22) and I am completely open about it although she took off 2 years ago to another state and now we are fighting for his rights to see his little girl. 
Anyway, his mum and I had butted heads since day 1. She would play nice in front of my partner but would attack when he was not around. He does not have a fantastic relationship with her either. Christmas time me and my partner had a massive fight and long story short I came home from work to pack my things and he went for a walk. His mother flipped on me and beat me. I am a security guard so I know self defence but as I was in my uniform I did not want to have the police around and see her in worse state and I lose my licence. She slung me around and when I had my back tuned she strangled me. I did not know I was actually 3 weeks pregnant at the time and the hospital did not detect it. 
Now, I am 19weeks pregnant I have made amends with his mums as I am trying to avoid drama and I have lost my mum so I still wanted to try and have a little bit of normality. But now.... after there constant arguing he turns around and says "you know if your mum was here I would expect her to be in the room" then he said that because his mum was not allowed in the room with his first that she has a right to be in while I give birth.. and said that that was final. I tried saying that I only want him but he is adamant that his mum is coming in 😫😫😫😫 
I have tried calmly saying that I just wish to have him as I don't know his mum and she has no respect for me. And if my mum can't be here I won't have anyone else's mum there. I am emotional and miss my mum as it is, I know I am going to be emotional and just want it to be an intimate experience. 
She power plays him and manipulates him all the time... 
I just don't know how to go about this... most days he hates her but I don't want to risk the day I go into labor is the day he wants her to be in there... 
I love him and respect his wants but this is one thing I will absolutely not have !! 
**UPDATE**
It brings me great relief to update this status on a positive note.
My partner has come to his senses and seen his mother true colours through her manipulating ways.
We no longer have anything to do with he and my partner stood up for me and said she is not to have anything to do with us or this baby until we see she is mentally stable enough to not come into our life causing drama. (Not that I have anything against mentally unstable people, she has just caused nothing but heart ache to myself and partner, even went to the extent of pretending she was going to die just so we would come running back. We are not heartless so we went to the hospitals and the nurses reassured us she was fine) 
Anyway. Yay. One less stress
