My girlfriend [f23] and I [m21] have been friends/worked together for about 3 years, and started dating a month and a half ago. We want to live together over the summer, but her strict Irish-Catholic parents [m, f 53] are against any of their daughters living with a man without being married. Her sister [f27] is already ENGAGED and getting married in a month, and their parents refused to let her move in with her fiancee before the wedding.

My girlfriend and I are both graduating college and commissioning as officers in the military. We're shipping off to separate bases in September and we probably won't see each other very often, at least for a while. We really want to spend this quality time together over the summer. My girlfriend is saying that she doesn't care, she'll live with me whether or not her parents approve. She insists we're leaving anyway, it shouldn't be that big of a deal, and that they can just "get over it".

However, I want to establish a lasting relationship with her family. They are a HUGE part of her life and I believe having a good relationship with them will be key to a good relationship with my girlfriend. I have a good rapport with them so far and I don't want to mess it up. 

How can I go about this situation so as to appease her family's concerns while still moving in with my girlfriend?
