<human>: Can you give me the gist of the text in a nutshell?

My [21F] boyfriend [27M] of almost two years is moving to a city 6 hours away for work.  I have to stay here because of school for at least a year and a half. I'm devastated and would really like to know how some of you have dealt with long distance.  A lot of people tell me that long distance never works and I don't want to believe that. 

My boyfriend and I are very serious.  We do not live together yet because he has not been able to find a job in his field so he was still living at home. We have plans to be together forever.  We both want the same things out of life and he's great. 

He doesn't want to go to this new city because it means moving out and moving to a new city and a new job all at once.  But he knows that this is his only option at a job in his field.

Ever since he told me, I've had this terrible sad feeling in my stomach.  I can't tell him how sad I am though because he needs me to be strong for him.  He needs me to tell him everything will be okay and that this is the best thing for him to do (it is). I've been acting happy even though it's eating me inside. Maybe I'll feel better once it's happened and I know how it's  going to be.  

I'm also scared that I just won't have the time and that's why it won't work.  I'm also moving out in September and I have school and a job and I do volunteer work somewhere where I think I could get a job soon.  I don't know how to manage a LDR on top of it.  But I have to.  

I'm just looking for some advice on long distance and maybe to talk to some people in my shoes so it can help me get through this.  Thanks reddit.
