Infinity Land,
If you do decide to head north in search of an aviation job but are NOT successful, will you be able to get your old job back easily or a similar job? If you are on a good income now you may be able to buy your own plane eventually and still live comfortably.
I was with a girlfriend for a year before I started flying for a company. After that I was away flying every weekend (which is when we use to do stuff together) and also during the week, so it just didn't work out. It all comes down to how much you value your relationship, and how much your partner/girlfriend wants to support your career.
