Dear zumzum,
Your first and biggest problem is converting your American girlfriend to your American wife so that you can even start the processes to qualify for the visas to come here.
As other posters have pointed out, the US airline industry is removing airframes from service faster than pilots are retiring, so there might be a job here or a job there, but the overall trend is still very negative.
I'm afraid that "British Guy" with that flair for colorful language that most Brits seem to posses, has it pretty well right.
Buena suerte............
