From the reference to the mistress I guess this is probably a joke. But it's in really bad taste, and callous to those who might be in actual distress.
Well...it's text, can you really tell if it's a joke when it's not someone you know? Seems the callous might just be instead to start hanging on this poor soul for doing something bad when maybe they're just expressing how they are right now. Extreme situations can make people extremely disinhibited and honest. Better to err on the side of caution and not give this poor soul more burden next time! :) ;p
