My future mother in law

Amber • Mommy to a beautiful baby boy.

I am 32 weeks pregnant and my future MIL has started taking over..it started with her buying the baby a couple sleepers every now and then but has now turned into her trying to make every decision that I'm supposed to make or at least have a say in. At first we talked about the nursery and I picked a theme and she said oh that's so cute, but now a few weeks later she took everything that we had in layaway out and decided that she wasn't okay with those items because they aren't what she wants she wants the theme to be something else so now she bought a crib that is red and has chunks out of it, so I wanted to sand it down and paint it a more neutral color like light gray but when my fiancee even mentioned to her that I like white and grey she got all upset and said but the crib is red, and we aren't changing it..she also brought home an outfit and said this is the one we are bringing him home from the hospital in...i know that I should be greatful because she is spending her money on things but she is completely taking me out of the picture and doing things her way or no way and when I buy clothes for the baby she gets upset because she didn't pick them..i really want her to at least let me have a say in things but she won't even let me pay for the stuff he needs because that's not the way she wants it set up..and I'm scared to say anything because I don't want to upset her but it's really making me feel like I dont have a baby of my own I'm just carrying him. I want to ask her to talk to me about things or to back off a little bit but I live with them and I feel awful for being upset over something like this when she's trying to be helpful. Has anyone else went through this? And Is it just my hormones making me overreact?

Update: She threw away all of the clothes and everything.
