<human>: Give me the gist of the text in a nutshell

Redditors I need your advice

So here's the deal. My gf (22) and I (25) met in college. We've been together for a almost 2.5 years. We've had our ups and downs like any other couple.  A little background history: When we were about a little over a year into our relationships my gf moved away for an internship (for 8 months). We tried to break up and but instead opted for a LDR. Sadly we both cheated on each other and broke up. We did the whole on again off again thing. After taking some time apart we decided to try again. And the past year has been great for both of us. We're very much in love and have even imagined our lives together for the long haul. Sadly things are about to change. She's about to leave again once she graduates. I've got a great job that will keep me in the current city. 

Now here lies the problem: I have this lingering fear that if she moves away we're going to eventually break up because the LDR thing will be too much. This fear is like a bothersome fly that won't go away. She says she wants to be with me and that we'll try to make the LDR work but im just not 100% convinced. So what should I do reddit? How do I make this feeling go away? Should I end it now so that I wont have to deal with the misery of breaking up after wards? I've told her how I feel and she says she cant give me an answer for what might happen in the future but I know she wants to be with me.
<bot>: GF is going to be moving away. LDR didn't work in the past and im worried it wont work again. Advise please
