I worry I’m locked onto being attracted to my ex forever

When I met my ex, I thought he was cute. Wasn’t totally sure about him straight away but after a few dates, all of a sudden he became the most attractive man to me in my eyes. He was attractive, but had this roughness around the edges, his wonky teeth, his long hair. My body for the first time in my life, desired him so much. I thought I was asexual before I met him, I was getting worried about that. But with him I enjoyed sex, with passion, and I enjoyed every day I spent with him. The love feelings felt amazing. We just clicked and he seemed well obsessed with me too.

But over time, all my feelings disappeared. I got depressed. I don’t know if I was depressed because he just didn’t do anything for me. He never took me on a date or anything. He became cold and distant and I stopped desiring him sexually. I panicked I was broken

I’m a year post breakup and even had therapy, but I still look at photos of him and want him so bad. I wish we could lay in bed talking about everything, singing songs in the car. I can’t believe it’s been a year and I feel so alone and worried because no guy I go on a date with incites the same feelings he gave me. I’m worrying I’m asexual again.

I bumped into my ex the other day, and I was so happy to see him. There was no awkwardness at all. But I came home and felt empty, I’m worried I’ll never love anyone again
