I agree with PolishPython...My parents got married when they were 18 & 21 years old...32 years later they are still very happily married. I have been with my wife for almost 7 years (dating included) and we are now in a similar situation as you (although her parents really like me). We moved to OH for her schooling and now that she has completed her education, she recieved a job offer from a firm back in PA. After a long discussion, we decided it would be best if she accepted the offer. Now until I find a new career back in PA, we are stuck doing the long distance relationship thing. We just alternate weekends visiting each other though.

May I ask why her parents hate you? I have to assume there is a reason?

If it's meant to be, you will make it work.
