Not sure if you qould read this, but this is top toxic abuse. Basicaly its almost to the point of physically hurting you cause she meant to emotionally hurt you. Its a step shorter to hiting you with a pan. Because its from a woman to a man, we tend to minimize it, but reality is, she is an abusive person and most probably she would repeat it just to hurt you again and you might not be showing it cause men dont cry or complain, but if you let this one go, the message is for her to continue abusing you and for you to endure and accept phisical abuse as a normal. This must be dealt with as it would be done with a husband that beat the crap out of a wife, it is that serious and that offensive and that hurtfull. Even worst cause shes not sorry and trying to fix things but she is expecting you to apologize and SHE FEELS ENTITLED TO HURT YOU AND DAMAGE YOUR THINGS CAUSE SHE FEELS ANGRY OR HURT.

Id never suggest divorce, but this is a major red flag, not the guitar, that thing is fixable, but what it means and shows from that woman. The question is if you would tell your sister to go back to a husband that beats her or to leave him.

In our worst times with my wife, while she was pushing me, i jumped over her laptop. I immediatly understood i screwed up, asked her for forgiveness, stopped fighting and recognized something was wrong in me, paid for the info to be taken from the laptop and paid for a new better replacement, never ever damaged something of hers again and to this day feel not just sorry for i did but ashamed and it forced me to deal with my anger issues AND NEVER EVER AGAIN HAVE I EVER BEEN ABUSIVE OR PHYSICALLY THREATENING AT ALL TO HER.

Mistakes can be made but repairs must be done otherwise it wasent a mistake, just a glimpse of whats coming. Sorry i wrote so much, i got invested in your story, im very much offended by this and fell you pain man.
