You are in a sticky situation lifesaver. Here's a true story to kind of put things in perspective (sort of)...
My great-grandparents came from totally different backgrounds... my great-grandma came from a very-well off family. She was going to COLLEGE (which was so, SO uncommon in those days for a woman). My great-grandpa came from a poor family, not enough money to buy more than 1 pair of shoes a year per kid. I'm still not clear on how they even met... BUT they did. And the fell in love.
Well, great-grandma's pop thought that would-be great grandpa was "below" them because of his lack of finances.
He threatened to cut off all of great-grandma's finances, including college, if she even
thought of marrying this guy!
Well, since I refer to them as great-grandma and great-grandpa, it should be obvious that they
did get married. And were so in love it was unreal... their entire lives.
Unfortunately, great-grandma's father
did stay true to his word, she got no money for college or anything else, and I hear it was years before they even spoke to one another.

So, the point of my long story... it is very possible that her family
will freak and pull the cash flow, and maybe even their emotional support.
At the same time, it's just possible that you two are supposed to be together (like the new John Cusack film), regardless of her family.
I think JustaMom was dead on with the 'remove the sex' theory. If there's still something there, try telling the friends and then meeting with the folks. (Taking it slowly, not all in a day or anything!) But her parents are
not going to respect either of you if you lie to them.. especially for
six years! And you have to understand what it means for her to be in school for like 10 years.
I will end my long post with this- a quote from one of my old high school friends:
The only things we regret in life are the chances we didn't take
