I understand you're finding this very stressful, but you need to try and take a deep breath and listen to what people are telling you, and try to understand why they're telling you those things. Its all very helpful information.
He makes enough to support you, while living with his parents. The person looking at your application needs to see that if something were to happen (ie, a fight and him getting kicked out) that he could support you both. If that were to happen, from that persons POV, he couldn't support you on that salary alone.
I had a wedding planned and booked for last year, and I had to cancel it because my fiance was in the middle of training, and wouldn't be hired by an airline yet and obviously wouldn't make enough to support us yet. We've been together 6 years now. STILL apart. It sucks, but in the end it will be worth it. I know its very hard, but you need to try and remain level headed and open to what others are saying.
As I have said we have a church booked in england for august 2nd of this year. But, we're seriously considering if he gets time off before that, him and I going to a Sandals or Beaches resort and getting married and just applying for a spouse visa. Its cheaper on the long run(which with your financial situation, you need to especially be aware of visa fees) and that way you can look to get a job the day you land, and perhaps if you push the wedding off a bit, get hired before moving there. Plenty of people here have had job offers before moving there on a spouse visa. Its not easy and most employers probably won't do it, but...at least this way you can print off jobs you're suitable for and show them you're actively looking.
It was such a crushing blow, when I had to cancel my wedding. But, sometimes life isn't easy peasy and you have to wait and get things more in order before you get what you want.
It also might have helped if you had savings yourself? You've been there almost 6 months not working, correct? My fiance and I would love to have spend that much time together, but we simply wanted to save as much as possible, so ended up only ever spending 3/4 weeks at a time together, so we could both be working and saving.
