How I met my husband who is not a pilot but a mailman?

"He always tells the children the story of how I went after him by sitting by the mailbox every day, and naturally I laugh and let him, because I like for people to think what pleases them and makes them happy." Edie Pg 146
From the title, it's clear that the story is about how the speaker met her husband. Throughout the better part of the story she describes her relations with this man who was a soldier and currently flies planes for a living. She discusses how they first meet then their encounters after that. This also includes a big scene where they are making out then he abruptly stops and tells her that he will write her to inform her of his new location. He will leave his previous lover, and they will meet up and live happily ever after. Or so she thinks. In reality this pilot is nothing but a giant womanizer. First he shamelessly flirts with her and gives her her first smoke. Then his old lover appears and he seems completely disinterested in her. Finally he makes a move on Edie, but leaves her, never to be heard from again. Not to mention he is hitting on a fifteen year old girl. Then out of nowhere in the last two paragraphs we meet this character of the mailman who BAM! she ends up marrying. What the heck? The story definitely has a surprise ending, but I think spending the majority of the story describing this other man has a deeper meaning. It's obvious that she really cared about this pilot and that she had feelings for him. Maybe because she spends all this time describing the pilot, it indicates that she still has these feelings for him. The mailman is only briefly described because he is not the biggest love of her life. Also the last line is ironic because the mailman believes she was pining for him but in reality she was waiting for a love letter from another man. I also believe that's the reason the story is called How I Met My Husband instead of How I fell in love with my Husband. I don't think she truly feels passion with the mailman, but instead settled because she was hurt. I believe she was really in love with the pilot.
