<human>: Can you give me a shortened version of the text?

I met this girl on Okcupid after being on the site for a couple of weeks. I noticed that she liked ping pong and after a couple of messages we decided to meetup and play ping pong. The 'date' went amazing. She was funny, smart and laughed at all my jokes. I found out that just like me, she doesn't smoke, drink or party. We only played for about 30 minutes and spent the rest of the day talking. 

We kept in touch regularly, even chatting for as much as 10 hours a day. We planned another date to see a movie. Even though she wasn't really into movies, I could tell she really had fun. That was Wednesday last week. We continued chatting regularly and I was certain this was going places because she actually seemed to like me more than I liked her.

Fast forward to Monday, and she starts acting distant, only giving me one word replies and just not being the same person. I ask her to tell me what's wrong and she tells me she really isn't feeling it because she thinks we don't have the same passions (She's in an orchestra, enjoys classical music and music festivals). I explain to her that I'd be willing to share her passions with her which I was really genuine about and she then goes off and starts talking about her OCD and how she wants to find the perfect person who shares her interests and passions. I do my best to convince her that the chances of that happening are very slim. After a long and peaceful back and forth, she just stops replying despite the fact that she was still online.

I don't know what else to do. I was certain that she was perfect for me. Our personalities are perfectly matched, just not our passions. Are relationships solely built on passions and interests? Is there anyway to salvage this?
<bot>: Everything is going great with girl and she concludes that she can't date me because we don't share similar passions despite the fact that she showed a lot of interest before.
