Swimming the Atlantic
Duke has a point. Don't be overly attached to her. You need to adopt the mindset that you can easily find another woman who would be interested in you.
Once you have a successful hit on another woman, you'll feel like a whole new man. Trust me, I've been in the same situation. Got super obsessed with this girl for a whole year. Literally pushed everyone else out of my life for her. When I realized what I was doing and when I saw that she was not my kind of girl, I killed the relationship. Obsession is indeed a cruel beast. Don't become victim to it.
