In any case, now is the time to make a move!
With unemployment at, what, 3.7%? The OP should be able to find a promotion* that allows her and the BF to try cohabitation, cut the brutal commute, and move on with their life plans. If you wait until a recession, the job move could become harder.
Be aware that cohabitation is arguably the hardest part. Living with another person’s habits, messes, smells, clutter, sleep disturbances, and style is VERY hard when one has been living on one’s own terms for a decade or more. Many LT relationships break up due to the thousands of little annoyances they discover upon moving in. But take the plunge, it’s now or never.
*why settle for just another job ;)
