Wife Threatens Divorce if I Don’t Delete Pics of Scratches/Clawing

My (M26) wife (F25) is telling me that our marriage is over unless I delete photos I have of her scratching and clawing me, at one point also causing bleeding.

She says it’s the only way we can “keep trust with one another and start a clean slate.” I told her that she would need to go to anger management therapy and she said she only would if I delete the photos right then and there. I also have my doubts she actually would go because she doesn’t think she has any problems.

I’m keeping the photos because she also falsely accused me of shaking and hitting her (completely false…I take her hands off of my arms!). I feel like keeping the photos is simply safety for me if she starts telling friends and family she was “abused” in our marriage.

What are thoughts? Am I right to reject her demand to “save our marriage?” Is this the best time for me to accept it’s over? Thanks!
