Still in love with my ex...

My ex and I dated for a year. But when we broke up we remained close by each other and continued to have a relationship without the title. Fast forward now to 2 1/2 years and we're still friends and hook up occasionally. But I'm still so in love with him. I think about him everyday and still crave for his attention. I just wish that by now that feeling would be gone. We have dated other people since but my feelings for him are still there. I just don't know how to let go yet. I love him so much. 😞
