<human>: Can you condense the text into a few key points?

It's difficult to type this all out because there have been a lot of things that occurred throughout this relationship that's deteriorated over 5-6 years. There are three significant parties: Me, my ex, and my ex's parents. I'm a 23 year old male and she is 23 as well. I guess I'm a bit confused with how it should end.

My ex and I mutually and officially called it off as a couple after some talks in a brunch diner, but we were still attached to the point that we agreed on a friends-with-benefits deal while putting the management of our careers first and foremost before our relationship. We had a distance relationship going-- I wouldn't say long since we were physically only about 2-3 hours away from each other, since I went to school out of the "Big City". 

These are the weaknesses that I've encountered at the moment, and I would appreciate your insight:

Sex is a hard thing to give up with her, since we had no qualms on both sides about it. However, I was more supportive to abstain from all sex altogether since it would only be hurting us on the long run, and that I felt it was unfair to me since I felt I was getting the short end of the stick. It was also unfair to potential girlfriends if I was screwing my ex while dating or attempting to date another woman.

We agreed that we would be close friends, and in my mind, repackaged the whole relationship to be identical to a relationship that would break if one of us found someone else, but in the meanwhile would be a kind of "limbo" relationship. We would do things together, like eat out, have fun, etc. like a couple, but the main reason why this would have any benefit at all would be the effect of "protecting me from her parents" according to my ex. 

I didn't want to close the door on us, and we both wanted to leave the door open into the future to be together again if circumstances changed.
<bot>: My ex and I (24/23) have broken up after a 5-6 year relationship. I'd like to know how to end the relationship, and whether a friends-with-benefits deal works.
