what would you do?

you've been spending lots of time in an online forum, getting to know people in there, getting close to people in the forum, and then after over half a year of knowing those people, one who is rather close to you left your friend a message to pass on to you:

"hey, i'm never gonna show up again... are you sad? hope not. hehe... don't be sad okay, because then i'm gonna be sad... alright... i'm tired... by the way, you were having fun when i was around, weren't you? if you weren't then i'm gonna go with regrets... hehe. alright... bye."

if you get a message like this, what would you do?
