"一面之交" doesn't mean much. There is no need to

speculate.

That a man and a woman can get married requires a lot more than facts 1, 2, 3. They have the "缘分". You don't. I am sorry to be straightforward. I don't mean to hurt your feelings. If you two had got to the point of getting married and you gave up because of your job and location concerns that would be a different story.
