I am irresistible to my partner and she/he is attracted to me.

Somebody likes the laugh you have been apologising for since school. Somebody finds your worst hair day worth remarking on, favourably, and means it.

That is the strange part of being wanted by one person for a long time: it doesn't track the mirror. It tracks something they have been assembling for years, to which you have no access.

There will be days you cannot see what they see. Their view does not need your agreement in order to be accurate.

Take the compliment as reliable data about them, if not yet about you.
