You guys don’t reach out even you think of someone?

We haven’t talked in years. I just saw them posting the picture that I sent to them years ago on social media as a hint of reminiscing - I will abbreviate the content here. The message was pretty outright and obvious that they are reminiscing or even fantasizing. I know it might be a moment of lust. I am astonished tho they still remembered the little things or details we talked about and saved them, after many years.

So you guys just rather reminisce by yourself or even vent about it on social media than actually reaching out?
