I don't approve your ex boss behaviour but sometimes companies struggle to get your pay check at the end of the month, it really depends on companies.
One advice: Being "good with computers" does not means that you're worth a 75K wage. When someone in India does Rails apps cheaper, you need the skills to prove 75K and even more. Having a college degree proves that you've learnt the basic toolset to be able to solve problems, however you can learn it on your own. Your challenge is to prove you posses those skills without a diploma. It's possible, I'm a drop out myself, but it's takes time, effort and networking to get there.
