I'm going to doubt you "accidentally" saw a post from 2013. It makes me think that maybe you are having some concerns about him right now?
If the only thing there is - would be a post from 2013 then it's likely he was vulnerable then. No matter what she did; however, the words he used in such a public forum are not respectful.
Is there something else you're worried about given you were looking through his time line?
