<human>: Can you give me a shortened version of the text?

So I've been dating my gf for almost two years now and as our schooling is winding down and we are getting into our careers the questions of marriage and cohabitation popped up. I've never lived with another person outside my family and she's been in college dorms. I want at least 1 year before marriage for us to live together. She was unsure of my opinion on the matter; she wants to move in nearer to a wedding date or sometime after. To be clear we are not yet engaged. I plan to pop the question soon but I am unsure how to proceed in light of some recent information.

Her mom says that, "That living together before marriage is just not how it's done. I would not support you two if you decide to do something like that," 
This was information was passed to me from my gf. My gf says her mom would be fine with a month or two before a wedding but any time frame longer than that is absolute no. Her mom still pays for school for now, but gf only has roughly a year left. 

My mother agrees with gf mom, that i need to be patient and wait for the appropriate time to move in. Same thing with no support if we go ahead and move in anyways. 

Everyone's telling us, "No," I honestly want the year to get accustomed to each other and I feel that marriage is something that's very serious, so you need to take pre-caution before committing to something so long term. I'm convinced she's the one I'm going to marry but I want to move in before. 

Any advice on facts or stats for cohabitation? Anything i can say to convince them otherwise? 

I'm also afraid her mom may sway gf's position from moving in a year before or not.
<bot>: Gf and I have discussed marriage moving in, family on both sides disapproves. Need to debate them otherwise, to be ok with it or at least not disapprove as much.
