Hang on a minute, this guy texts her to tell her that he's been banging some other bird and you're suggesting she has a warm fuzzy chat with the fuckwit????
Correct, we've established he's stupid but he might just have been stupid and drunk for example, or a practical joke or some other unlikely but possible reason.
Can I suggest you biatch slap him
After she has a chat with him, i've seen some pretty crazy mistakes done thanks to the fact that some particulary dumb bugger decided to make a practical joke via text message.
