I think you may need to look at it at a different view. You may not have been the problem. It may have been your choice that had the problem.

In other word, nothing is wrong with you. Sounds like she had the problem. Be thankful it is over and happy to move on, even though it may hurt. In the long run it would have probably saved you more grief. If a lady cannot accept you for who you are then they do not deserve you. You sound like a awesome guy and you will find that lucky girl soon.
