You have to make a few lifestyle choices first.
You either decide to follow you heart, be poor for a while, and look seriously at being the single man about town. I will say it's fun for a while but eventually gets pretty lonely and you will probably wish at some point that you'd stuck with what is good on the girlfriend side of things.
In your position, id keep making the bucks, and if instruction is something your into, move into that part time while you work towards twin/ Ifr etc.
You will get to a point in a few years where you will have the best of both worlds and be able to make a choice. This path is the long road time wise, but means you get to keep your life..
Depending on your free time I think a year whilst working full time is a stretch but if your a FIFO could be possible.
