Complex #5 - progress and throwbacks

[Complex]

OK BAD NEXT STEP IN MY SITCH:

W wants me to take her car for an oil change. I go check her car and the navigation map is asking for a pin. Looks weird bc it never did that. So I suspect W knew I'll take the car and locked it so I can't see the history.
I go and ask, why is this off and asking for pin, you don't want me to see where you have been?

She completely freaks out that I accused her for that. I stay calm during the whole discussion. I try to calm her down. She was incredibly upset that I accuse her of things. Showed me evidence that I'm wrong and where she has been recently and not with OM. I feel like sht. She freaks out more, grabs my Greencard paperwork and starts filling out. She tells me she can't live with me like this me accusing her, stressing her out. Now I look like the big idiot who is a freak making assumptions, not letting her live her life, pressuring her.
Partly true but I got so much better about things. She sees a weak crazy guy in me. And yes I feel like [censored] right now and really tried to not say too much and stay calm and I did. But it's all my mistake for not letting it go and doing my own thing, letting her life the life she wants.
I failed DBing feels like. I'm so down right now. Maybe it was inevitable. But I hit rock bottom AGAIN! And she hit rock bottom annoyance again that now led her to the next step towards divorce. I screwed up once again and W is just so annoyed she just wants out so bad. God I hate hate hate my life. How do I FKN deserve this????????
And now the worst part:

She took off to tell her dad that she will divorce me.
Wtf!?!?!????

Help!
