Mother in Law 😤

💙💖
(My mother in law is deaf, stating this now so I don't have to repeat it 800 times) 
My [future] mother in law is an absolute nightmare. We are currently staying with her while we get back on our feet. I'm a little over 2 months pregnant, already working one job, looking to take on another. Fiancé doesn't have a job yet but he too is looking. 
When we found out I was pregnant, she was thrilled. However as it has gone in she has started to overstep her marks. When I went to the OBGYN, she demanded to go back into the room with my fiancé and I. She was all around the room, signing all sorts of stupid shit, and making me a nervous wreck. Finally when my doctor came in, did everything and gave me the ultrasound, she told me afterwards I wasn't allowed to post the ultrasound until she said so. I posted it when I wanted (almost directly after) and she got all mad and bratty and wouldn't talk to me or her son. 
She's also a huge hypercondriac. I have a nail biting habit. She told me that "I was hurting my baby", and later on, I was laying in my boyfriends lap and he was twirling my hair with his fingers. Again, I was "hurting my baby", and she slapped us both on the leg. She tried to tell me naps would hurt my baby. When I showed her PROOF that pregnant women need naps, she got all offended. One day after a nap, she asked me what I dreamed about (fishing on a boat with my fiancé), and after a second, she looks at me and signs "Stop dreaming. You'll scare your baby". 
When she found out we were getting married, she immediately assumed that all of OUR wedding decisions had to be approved by her (even though my parents and grandparents are paying for all of it.). My wedding colors are silver, white and red. I wanted to wear red shoes, since I'm wearing a short dress and I want my legs to pop. She told me I wasn't allowed to wear red shoes. I had to wear traditional white shoes. She also told me I had better have my nails done, hair done, and lay in a tanning bad. I told her I was not laying in a tanning bed pregnant. She once more rolled her eyes and went in a bratty pissy mood. 
She's also trying to manipulate our name choices. She told us she thinks our names for the baby (Lucy Rose and Gabriel Grey), are stupid and to pick new ones. 
Tonight was the last straw. I needed my phone charger, and she was plugged up into the other charger (it's one of those blocks with two USBs, one for my 6, one for his 4). Her charger was on the counter. When I asked her for my charger she didn't want to give it up so my fiancé stepped in. Finally she threw it at me, and it hit me smack on the ankle bone. 
I'm at my wits end with her. I need to get out of this place. My fiancé takes up for me as much as he can, but we can't get away from her. She follows us everywhere nagging and bitching. I want away from her before my baby is born, because I'm holding back smacking the ever loving fuck out of her now, but if she starts trying to tell me how to parent then that's it. Sorry for the long post. Just needed to rant.Â
