Okay, it's my turn now.
Satisfied or not, it is up to them to feel that way (or not).
My personal metric is based on the fact that after the relationship STILL maintains pleasant semblantres and attitudes to dating. As a less well-known example.
Since I do not see them crying, sad or like yesterday breaking the tent, the signs for me are that YES, it worked and it worked.
But as I always observe here, this is my personal opinion that can be collective with others or just individualized with my person
In other words, my "metric for satisfaction and desire met" is my metric for satisfaction and desire met
