One of reasons I was without a pair since 22 to 29 yo age is my vow to have no other woman until 30 years.
I tried to explain my emotional state to the one I had feelings to.
As I've not seen serious interest to me, which thought should be obligate to appear soon when your "real love" pair is met, I stoped communications with her. Despite I had significant feeling for next several years.
It took 17 years from the moment I've got significant feeling to one woman to the time when I got significant feeling to other woman.
