<human>: I met my girlfriend in a play we were doing together in 2014, where I played her romantic interest (cue alarm bells). We hit it off pretty quickly, and before the show was over, we were going steady.

We've always been really comfortable with each other and our sex life is great, even though we both admit that we're totally different. Recently though, those differences have been niggling at me. Although we rarely argue, we also rarely agree on anything. At its core, our basic world views are vastly different. 

At first, I put it down to opposites attract, but more and more, I find it's putting up a wall between us. I know there was a time I really loved her, but the more I think about it, the less I think I feel that way. 

All this has come to a head, because we had THAT conversation a few days ago. The one about the future, and where we are going. Basically, I don't want what she wants (a house close to her parents, white picket fence etc). I told her that, but the next day we acted like the conversation didn't happen. 

Now the niggling, has become a huge problem in my mind, the comfort is gone, and I'm really starting to believe I don't love her anymore. Should I tell her how I feel, and perhaps break-up, or wait a little bit to see if this is just cold feet? Whatever the case, I care about her immensely, and though I know she isn't fragile, I don't want to hurt her, especially when she's going into final exams.

Can you give me a shortened version of the text?
<bot>: I don't want the same future as my girlfriend. The more I think about it, the less I think I love her anymore. Should I wait before I act, or is this not just a phase?
