My girlfriend works too much, should we stay together?

My girlfriend just started this job 4 months ago and about 2 she started to work everyday 12 hours a day, she's always sleeping and working and barely has time to see me, our relationship has become text and call, is it worth it to stay together? She is saving money to go on vacation for 3 months with her family and school when she comes back from vacation.
