re: I can predict from FB posts which of my female friends will leave their husbands

These are obvious signs that the couple is splitting. This isn't magic. When I divorced, i never made a public announcement on Facebook, and had more friend pics & activities posted after that. I'm sure the friends who don't know me well were like, "who the eff is this?" & thought it was sudden when I posted a picture with my boyfriend, even though it was more than a year after I left my ex.
