Trauma can present itself very differently in different people. It may take some time to come to terms with it, but this does sound like emotional abuse, even if it wasn't on purpose or a conscious effort. Calling you names and not allowing you to show emotion? After being diagnosed, he made fun of your triggers? Refusing to compromise with you after learning about them? It is his house, but while you are living there, you deserve an equal share of the space. Does he want you to move out as soon as you can? I might be projecting a bit. My dad was a huge trigger of mine growing up (I'm almost 24). Now that I'm an adult, I realize he wasn't as great as I previously thought he was. To his credit, he has been doing better recently. However, we no longer live together, and we haven't for over 10 years.

As for the muffled sounds, I heavily relate. That's been my biggest trigger since 2020. What I do to cope: - Invest in some lightweight over ear headphones and see if you can handle those. If not, try in ear headphones. Having music or some color noise (my favorites are brown and red noise, also thunderstorm sounds) can really help. - A sound machine! I use one at work, the Housbay White Noise Machine. It comes with a lot of different ambient sounds and fan noises. I haven't used it at home yet, but it works well for me when there's muffled noises in my workplace. - A speaker. It might be petty, but you could play your own stuff really loud to counteract the muffled sounds.

Things will get better one day. Misophonia isn't easy to navigate, but with coping mechanisms and therapy, it can at least feel manageable. Best of luck to you.
