<human>: My girlfriend and I have been dating for over a year, have known each other for almost 2 years. We love each other, have good jobs, and really believe that we will get married. We recently decided to move in together in a couple of months. Both of our parents are catholic, and her parents are supportive of our decision. While it goes against Catholicism, they understand our decision and the reasons behind it.

My parents, on the other hand, are not supportive at all. My mother keeps pressuring me to get engaged and get married before we move in, and my dad told me that he disapproves of this 100%. My mom has been more warm hearted towards this than my dad, and she was very excited for my girlfriend and I when I showed her our new place. My dad seemed pissed off and hardly gave a shit. 

I understand that this goes against their lifelong beliefs, but I don't know what I can do (if anything) to get them to be more accepting. I hope that as time passes they just realize it is reality and move on, but at the same time I don't want to be disowned by my own parents. 

Has anyone experienced this before? Any advice appreciated.
