Hi Rachael,
This is how it will (eventually) pan out:
You will go through a few more cycles of this. Then, during the whole rest of the year he’s not around, you will meet someone. About ten years from now he will be alone and you will be happily married with a family. You will see him from across a crowded room and (are you sitting down?) he will look… Not Attractive.
Yes, he will one day be Not Cute Anymore. To anybody. And the “nine out of ten times there’s another female”? He’d be lucky to get one female. And it won’t be you because you will be glowing, happy, and adored by a man who deserves you.
Best,
Inky
