<human>: I have been with my girlfriend for two years this summer. We decided a couple months ago that once our leases were up at the end of this summer we would move in together. We typically spend about 4-5 nights a week together so it seemed like a positive step.

At first she was hesitant when we first discussed it but then she was totally on board. Saying stuff like, "I can't wait until we have our own place!" Last night we were talking on the phone and my roommate just found himself a new place to live with his girlfriend once our lease is up. I mentioned how much they were paying and general stuff about the area and I could tell something was off so I asked her what was wrong. She told me she was scared and wasn't positive we should do it considering it's a big step.

This led to me explaining that I love her and want her by my side in the future. Of course I'm a little nervous living with a SO for the first time but it's her and I know it would be great. She told me she "thinks" (that hurt) she sees a future with us but isn't 100%. 

I went out of town for 10 days for work and got home a week ago. While I was gone she went to a wedding of one of her college friends and ever since then I have been able to tell something was off. 

I feel like being together for two years I know everything I can know about her and moving in with each other is the next step, that's where we will really learn everything about each other. If we both sign our own leases and live apart for another year and then move in with each other next year and it doesn't work I feel like we have just wasted a year of our lives. 

She is coming over tonight so we can have dinner and talk about what's going on. I love her but know it's not fair to me if she's hesitant about a future together. I guess I'm just asking for some advice or questions to ask tonight? I always feel like I know what I want to say and then just blank and forget.

Can you condense the text into three sentences or less?
