She's probably upset he left her and trying to break up your relationship. She doesn't sound very mature if she would send you information like this over facebook. Plus, people are usually reluctant to end marriages so they're generally pretty sure about their decision to leave. Give him a bit of credit and ask him about it without getting hysterical. I'm sure he'll appreciate you trusting him enough to talk to him about it rather than getting worked up and breaking up without hearing him out.
