<human>: I've known my ex for about 4 years and spent 2 of those years together. We were best friends before we starting dating and can honestly say that I she is my other half, when im with her she makes me the happiest person in the world. We make each other better people. But we broke up a few months ago. The break up was rough and unexpected (at least for me). I still have strong feelings for her. But I have moved on. I have been with 2 other women after the break up. But I can't seem to shake the thought of her from my head. I always compare her to every woman I am interested in. Thinking that my ex wouldn't have done that, or does that better. It ruins any potential relationship I can have. How can I stop comparing other people to her?

Can you give me a shortened version of the text?
<bot>: Can't stop comparing my ex to other women. Its ruining the chance of starting a relationship with someone new. What do I do?
