<human>: I am completely and utterly stumped at where to go from here, so I need some help weighing up each path.

Me and my girlfriend have been in a relationship for just over 2 years now, and everything has been as it should be. We are very happy with each other, we have had our fair share of arguments and fights, our sex life is great, and we consider each other best friends as a bonus. 

However, being in the same year meant we would both go off to uni/college at the same time. She is off to university, and I am staying behind to do a course elsewhere before continuing on to a university (not likely to be hers). We had previously discussed what we would do when the time came, and unhappily agreed that it may be best to end it on good terms rather than a possible bad break-up during a LDR.

I've never been so unsure of what I want out of this. I love her to bits but we don't know if we want to take the risk of losing each other as friends too if things go wrong due to stress. We are each other's first and I have been thinking about a lot of things, such as the experience of other people that we will meet (it will be completely new faces at both ends). If we broke up I would be very supportive of her meeting new guys, at least I hope that's how I'll be.

Some of our friends who are couples have decided to stay together, but I don't want to be influenced by it, but I just don't even know what I want to do anymore :(

I'm hoping you guys can just help me weigh the pros and cons of any decision, not necessarily decide for me if you don't want to.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Gf and I are going in different directions in about a week, do we stay together or call it quits while things are still good between us?
