<human>: Can you succinctly summarize the text in 1-3 sentences?

The summer after my senior year of high school, I had a thing with a freshman girl. We talked a lot and were very friendly towards each other and I started to really like her. I asked her to go to The Fault In Our Stars since that would tell her that I thought about her like that and to see if she felt the same. I put my arm around her at the end and she tensed up awkwardly. I asked her about it and she said she didn't think of me that way. 

I don't want to seem dramatic about a girl that I never even kissed, but it felt like I had a broken heart. I lost 10 pounds from not eating and I felt miserable. I got better eventually but it took a while. I was sad that it didn't work out because I thought we were good for each other and I also felt really embarrassed that I kind of fell for a freshman and she friendzoned me, a now-college guy. 

Fast forward to now and I've had a girlfriend for a year and a half. I could go into detail to legitimize the relationship but it would take too long. We're perfect for each other and we've been through everything and are still smiling. But I can't stop thinking about why that girl didn't like me back. I know that being older doesn't mean you can date whoever you want that's younger than you but a lot of girls are into that and her past flings show that that's what she liked too. It just makes me mad that I thought we had so much potential, she agreed to see a romantic movie with me, and then she didn't even give me a second thought. Maybe I'm not happy with my current relationship and I'm looking for a reason to get out of it by self-sabotaging but I just don't know. Any ideas?
