This was interesting. I like how it's ambiguous at first - I thought the protagonist was a hopeless romantic, expecting every girl he met to be "the one". In terms of format, I understand keeping it tight and not using paragraph breaks, etc. I would say you might want to go back and check for commas, etc. But again, that also might just be a question of style. Nicely done, and I like how the story stops at the perfect moment.
