TLDR of last post: I was a petty, childish asshole and wasn't letting my girlfriends parents sleep in the same bedroom at my place because they wouldn't let us sleep in the same bedroom at theirs.

Hey it's been 20 days, and I sort of forgot about this, but reddit auto logged me in and reminded me, and thought i'd give an update / ask for more advice.

So I read the comments, and it helped me realize from outside POV's that I was 110% being a petty asshole. I already sort of knew that, but hearing people with no connection to us confirm it helped open my eyes.

I pulled my girlfriend aside the next day of my post, and apologized, admitted I was being childish, petty, an asshole, and that I wasn't acting my age,, I was more like acting a toddler not sharing toys. She agreed and laughed at my analogy, and forgave me as long as I called her parents, which was my next plan anyways.

I called her parents, said roughly the same thing, and they agreed (did not laugh) and told me that they will find another date in the future and reschedule staying with us, which I told them sounded great, and we hung up. All was well!

But the comments, and some private messages helped me realize as well, that my girlfriends not taking initiative was something I needed to seriously talk to her about and stop letting go if I planned on marrying her.

I thought of how to say everything I wanted to, etc etc and a day or two later I decided to talk to her.
I told her how much I love her, the person she is, and brought up many things she brings to our relationship to start things out. I then brought up how if we are going to work more in a healthy manner as we get more serious and conjoined, things do need to be more equal between us.
So I wanted to work on a compromise.
I pay for everything, except 50/0 groceries, I do the majority of the cooking and cleaning, etc as you all know. She got quite upset at this, and was trying to say she doesn't have value in our relationship, but I tried to reassure her, and the conversation sort of ended there.

I stuck my ground and two days later, I brought it up again once the dust settled, and while the conversation was... Rocky. We worked on a compromise that she will ask her boss about the raise she deserves, will begin doing more of the cooking and cleaning. Not more than before, but more than me.
I asked her also if she would talk to her parents about the whole "trying to convert me thing" and well... Baby steps, not gonna happen yet.

Anyways, why I still need advice as well:
Since we had that last conversation I thought things would be better, but she's been cold. She's been only cooking really quick meals, like frozen stuff, mac and cheese, etc and I tried talking to her about it and that I'd be happy to teach her the stuff I'd make for us but she always says "If you don't like it, make us stuff you do", which is... Fair. But I KNOW she's as good of a cook as me.
I tried talking to her if things are stressing her out, she declines, I tried asking if anythings wrong, she declines, etc etc.
She's been cold, our sex life took a nose dive from once every two days, only twice since my last post.
I tried feeding into her love languages (She likes words of affirmation alot so i've been complimenting her extra and reassuring her) but she seems unintersted. I even tried asking her if I explained anything badly, or said the wrong thing about the conversations above, and she says no.
What can I do to make her feel happier? She barely even greets me when I come home now.

TL;DR:
Apologized to my GF, and her parents about last post. Ever since bringing up stuff that bugged me, she has been very cold.

UPDATE:
I am currently deciding to do two things as comments have suggested:
A) Spend a week doing everything for myself, by myself. Watch what I please, make just my own food, and finally take the classes I have been waiting for her to agree to (pottery, baking, etc) and just do my own thing and see how she treats it. My main fear being that she will just see this as petty, and that I'm doing the same thing as I almost did to her parents in my last post.

B) Try and talk to her one more time about all of this, which most likely she won't be receptive to. Tell her how I feel, what I want in a relationship and needs to change if it wants to work. I obviouslyl fear she will break up with me for that, but if she does it's probably for the best.

UPDATE**:
I think I will choose A. Try and give her a slight taste of her medicine, and then bring up how i've felt. Maybe she will understand better once she sees me doing my own thing?
