Who the hell is telling you you can't be married and lift?
If she can't understand your need to hit the gym for an hour or two out of the day, I don't think she's the right one for you.
Don't rush things from this point on. You have been doing a long distance thing, and that's great. But when she's in your pocket 24/7, you will start to realize all the little shit she does that drives you crazy. Stay engaged and live with her for a year, if you still are lifting as much as you want, and are genuinely happy, go on with it. If not, hit the strip club.
