my boyfriends EX

my boyfriends Ex posted about him on Facebook AFTER TWO YEARS OF BEING BROKEN UP.

It said "one day you'll find a girl who expects your flaws & insecurities that girl ain't me, I think you're a piece of shit" & tagged him In It butttt she's blocked on all social media accounts so he has no Idea. I only know because my friend showed me. Do I tell him? Do I just laugh about It?

Is he talking to her again?

UPDATE YA'LL THE BITCH SAW ME & MY MAM AT A PARTY AND STARTED TAKING PICS OF MEEE
