I can't do this anymore

First two messages are from a few days ago, next two are from right now.

A few days ago I was at work and when I left I simply said "ok sorry been busy" because I realized I hadn't seen her msg. I didn't realize Gemini popped up and blocked the bottom of one screenshot but all I said was "dang what?" And "dont start with me lol" to try to keep it lighthearted. I could tell instantly she was in a bad mood from the way she was texting. Came home and of course she started a fight over nothing (don't even remember what i did to upset her but it's always something) and so she just said she was going to bed. I slept on the couch because I was hurt. This is like a daily occurrence. I have to walk on eggshells.

This morning, she was using my car for Amazon flex and I texted to see where she was because I hadn't heard from her and my daughter has an appointment this morning so I need my car back soon. She instantly started giving me attitude as if I was personally attacking her. I was trying to not say anything more but when she said "I'll take my own car from now on" I knew what was gonna happen. It always happens. She replied after that last screen shot continuing to say she will no longer use my car and that I snapped at HER. I'm so done with this.
