<human>: I had a huge crush on this girl last year, that died down since I didn't make a move and lost interest. We've kept in contact since, and I've always considered her to be a friend. About a month and a half ago, I met her through a school function and we started talking again. We hooked up after prom (we didn't go together), and started hanging out and hooking up a couple of times a week. I realized that I still liked her, and I wanted to date her. She was initially hesitant to the idea of dating but she seemed to be open to the idea after a bit.

About a week ago, she stopped responding to my texts. Went radio silent for 8 days. Last night, she texted me and said that she wanted to end things. Her initial reason was that she thought I was clingy, but I didn't believe that was the whole story so I pried a bit and she eventually
opened up.

Basically, she claims that she never even liked me as a friend and she only tolerated hanging out with me because she thought I was hot and wanted people at school to know that she had hooked up with me. She ended things because she said that pretending to be my friend was really tiring.

I feel sick to my stomach. I feel incredibly used and I don't know how to handle this. I really liked this girl, and it turns out that she didn't even think of me as a friend? She was just faking that all along?

How should I respond to this? how should I handle it? Just forget about it and move on?
