I need to learn how to write less...

I can relate with you. My SO (Sarah) has a rather lengthy beauty ritual. In the end, I learned that her beauty ritual is not a choice but a necessity.
I see Sarah as the most beautiful, hottest, most wonderful woman I ever have laid eyes on, but she sees things a bit different. I am her cheerleader, but her rituals are a must. There was a time where I felt that her rituals and her looks meant more to her than me. My cheerleading felt one sided. I finally sat down with her, no distractions, just us. I told her, without beating around the bush, that I felt ignored and that I didn't matter.
I learned there how much her rituals meant. She told me that not shaving herself made her want to kill herself. Among other things, I learned that her rituals were crucial for her self esteem and happiness, and she also felt that she needed to do them because of me. She also second guesses her choices, makeup, and outfits, which makes her ritual lasts longer. She wanted me, and the world, to see her in her best. She wants to see herself in her best. What seems like optional stuff to me, is not an option for her. With time, her rituals have shorten because she finds what works, shortcuts, etc. Sarah and I still have these conversations, which I am glad we are open about it. She also promised to listen more to me and make me feel valued. We check up on each other.
Communicating helps out, and being direct too. Your feelings matter, and I don't think she is doing it in purpose. Talk to her, without getting mad and saying stuff that one might regret later, but use words that show your stance. I tend to be a push over, so I avoid words like, "kind of, maybe, sorta". She likes it that I do that, avoiding those words, but that is our dynamic. These are my two cents, but I hope you and your SO can work through it.
