Anyone else hate that you are supposed to throw away your exes like trash?

I really like my exes as people. I spent all this time choosing them, becoming friends, exploring common interests, laughing, enjoying their company. Sometimes you just aren't quite compatible in a forever way, and things come to an end. But I miss them and wish there was a way to be friendly. I'm not talking about the relationships where things were hurtful or there was bad behavior. Nor am i wishing to do date-like things again. I just want to talk, send the an article they'd like, and maybe make sure if they are ok. (One guy died unexpectedly).

Anyone else wish there was some socially acceptable middle ground?
