One option is to move on, and meanwhile - if he really loves you deeply he will make the lifestyle adjustment and then come back to fight for you - but don't dwell on this, you could realize you are much better off without him anyways.

Another option is to try to help him make the adjustment but I get the sense you've tried this several times and it hasn't helped. Is this correct? Could you do something different if you were to try one more time?
