I think the past has gone and you can't do anything about it....just try to learn from it and do not repeat them again....you are still young and you can make your life.....
and honesty, you are better off without that guy....it looks like the guy had so many issues!!!! you were lucky to get out of that relationship, but you did a bad choice of quitting your job.....well...you can't do anything about it now! Just try to find a job....probably, you can find a job in different countries or different states.....check in Craigslist....and good luck
