At this point you're participating in your own abuse. Your relationship is unbalanced and objectively broken. If you're unwilling to entertain any realistic solutions then you're wasting everyone's time complaining about it.
You should seek out real help, either a therapist or marriage counselor. There's no actual reason for you to stay in your current broken state. Your made up reasons are equal parts bullshit and naivety.
I wasn't going to jump into this thread and I don't want to turn this into "Relationship News" but, I feel like I need to let you know.
I grew up with divorced parents who were together longer than they should've been and let me tell you, kids know. They absolutely know when their parents are together but can't stand each other and what's worse, they may assume it's their fault.
I grew up with parents who divorced when I was 18 months old when it became clear they did not love each other anymore. But they both wanted the best for me, and didn't do the petty shit I've heard about other couples where they shit-talked each other to the kid or something. They split time with me evenly.
They both eventually got re-married and are very happy and I have no regrets about how my childhood went in that regard.
Seconding. Furthermore, please don't feel like you gotta stay together "for the kid". At least ask the kid whether they care. My parents asked me. I told them I didn't care.
Looks like you are less than 10 years into the marriage. Get out ASAP. You are stuck with alimony for basically half the length of your marriage. Unless it exceeds 10 years. Then you are stuck for life.
Wow, those are some crazy laws. Child support is mandatory around here, and follows well defined rules, but spousal support ("alimony") is much less well defined and (in my limited understanding) less common and shorter lived.
Edit: "around here" being Australia and New Zealand
