That's ridiculous: you're saying that either she puts up with a bad situation, or she leaves. What she did was basically say that she wanted a change. Doesn't matter whether or not those were her exact words: people say things they don't really mean when angry or frustrated and in this situation I'm sure she was both.

It's a pretty fair bet that the statement "get a job or get out" wasn't the first thing she said about the situation! And in any case we only have his version of what happened.
