Jesus Christ, don't you have better things to do with your time than worrying about someone who wants you to be their life support?
Shouldn't you be looking for a job?
If ANYTHING, consider this a BLESSING.
She did YOU a favor by dropping you like a bad habit because of something stupid like "losing your job". In today's economy, everyone's job is "unsafe" and if she wasn't willing to stand by you in such a dire time, she is NOT worth it.
I know some people will say: Spin plates, join a gym...
Which is all good and awesome things to do, but right now, you are kinda strapped financially. So I say, treat finding a new job as if it were your "daytime job" and at night, read a book, go out with friends, do some indoor exercises or just go out for walks. Maybe find a part-time job in the meantime to tide you over. Or something menial like walking dogs or plowing snow or whatever.
Just keep yourself BUSY.
This girl is NOT worth it.
And the sad fact is, spinning plates might be hard when they suddenly ask you what you do for a living and you say you are "Unemployed" (Because we know you WILL say that), you'll go through the same rejection all over again.
Time to move on. And be glad she dumped you for THAT reason.
