You were merely acquaintances. Not even friends, because a friend wouldn't "cut off" contact.

No bond at all. This is why you need to really, really make it clear that there was no relationship here to your doctor---I think you may be implying to him/her that there might have been one (because even you aren't sure), and your doctor might think you're going through a normal mourning period.

There is nothing normal about the age range of women you are trying to communicate with, you are setting yourself up to fail every time.
