My boyfriend became frustrated at work and resigned.
Did he say why he resigned?
Yes he explained that he didn't want to work for a shitty boss anymore.
It's awful to be frustrated at work, but quitting before lining up another job just over that is a bad idea. You might end up unemployed for a long time in that case.
You just don't understand, it's good that he quit.
I am happy that he got out of a toxic environment, I just think it would be better that he held on a bit longer until he found a replacement job.
