<human>: Can you summarize the given text in a few sentences?

I have been seeing this girl for 7 months and she is the first girl that I have liked in the last 3 years since my ex gf. She had a relationship of 5 years end 2 years ago and still is enjoying being single. We both were on the same page for a while but my feelings have evolved. I asked her about dating and she didn't want to do it. Beyond that she is going to Vegas in three weeks with her friends for the weekend. 

I honestly just want out. However I want to leave with dignity. What is the best way to cut this off? 

I wish it would work out but I'm coming to the realization that she never really wanted me.
<bot>: been dating a girl for 7 months. Treated her exceptionally and she still doesn't want me as a boyfriend. I want out.
