TITLE: Want to move in with my GF next fall. Any ideas on how to tell/ask my parents about it?
POST: I am 21 years old and a college student. I am still financially tethered to my parents for insurance etc. So, the argument that I can do whatever since I am an adult doesn't apply since I am not completely independent. 

My girlfriend and I have been dating for about 7 years now. We spend everyday together and we share between us 3 animals. We usually just stay at her place since it is where the animals are. So, financially it is dumb for both of us to have a place.

My parents are the type of people that believe in the values of marriage. Also, that a couple should be married before living together. But, they are also very understanding. The problem is they will play the disappointed card, I believe. Or something like " In an ideal world we just wish you were married first." What the hell?

Since we have been dating so long, we don't really see the problem of moving in together. I just need some tips, support, or personal experience from you guys.
TL;DR: 
I want to move in with GF (w/o getting married). My parents aren't super conservative but just enough. I need advice.
