Perhaps it`s not so much him that you actually need to get over, but rather, your own out of control emotion? Generally, in a going out together relationship context, you can only help those that most require it through friendship, but often it`s from behind a desk which ultimately proves the most useful.
If you`re able to separate your emotion, come attachment, from how wonderful as a person this guy actually is, I sincerely believe that this process will help you enormously - It has always worked very well for me!
