The worst possible thing you can do is take it personally and start beating yourself up over it.
This will eat away at your self-esteem and will repel any new potential suitors that might come along.
I know plenty of gorgeous, smart, funny, successful, amazing women who have had the vanishing act pulled on them and it didn’t make them any less gorgeous, smart, amazing, etc.
A guy can lose interest for any number of reasons and oftentimes it has more to do with him than with you.
Try to keep your ego out of your relationships as much as possible. As time works its magic, the best thing you can do is stay as busy as possible.
Your relationship status should never determine your worth as a person. Immerse yourself in work, spend time with friends, check out a cool new bar or museum, try out a new exercise class.
I have felt the beginnings of self doubt and sadness; and even anger.
