confusion

what would you do?

let's just create a hypothetical Person X and a hypothetical Person Y. the two met very briefly in person, and communicate entirely through the internet. and let's just say that last year, Person X and Person Y were tight pals on really great terms; good laughs, long conversations, etc. then one day, kinda out of the blue, Person X stops talking to Person Y. Person X no longer responds to Person Y's comments, emails etc. and communication just ceases. a month or so later, Person X kinda says sorry, they were busy. after that, all of Person X's replies to Person Y are considerably shorter than they used to be- from paragraphs to a few words each. Person Y loses hope, and doesn't contact Person X for a couple of months. then there is another attempt at interaction, and another failure. a few more months pass, and Person Y just wants to hear something, anything from Person X. Person Y just wants to know how Person X has been, and to let Person X know they still care. should Person Y even try, or will it just lead to another imminent disappointment?

this is absolutely no big deal, just feeling a little confused...
