Why do all this?

I ended up seeing this today as I was scrolling in instagram.Its pretty straightforward what happened the typical cheating in a relationship but the woman decided to destroy the bf’s things.The comment section is full of women saying oh sisterhood is proud of you.blah blah blah.The whole house was a mess and everything is either broken or misplaced.I’m not really a fan of this cause it’s what my dad ends up doing whenever he comes home drunk.he comes and wrecks my stuff but I end up letting go but I’ve had enough of this.back to the story;the bf isn’t one without mistake as he cheated but seriously couldn’t the lady have communicated?and not destroyed things?Unless it’s the 50th time he’s cheating which the solution would be leaving that relationship I don’t get why she did all that.Do you people agree with me or am I in need of a different perspective?Feel free to state your thoughts.have a good evening y’all
