First idea....IDIOT...or 3 times for emphasis?...He might have been in a bit of an emotional place too and wasn't sure if he sent it, if you received it...maybe he felt if you saw 3 emails from him you might peek at 1?
I wouldn't try and figure that one out if I were you...I think you got a great response...his drunken message may very well be his internal being trying to push through...the result may have stirred him up a bit with OW...thus the emails that she sent...now if she did in fact send them, then this tells you she has access to his email...so be very careful as to what you send out to him...
You are doing great...now enjoy what is left of the weekend...me? I am cleaning like a fool because we are having apartment inspections and with all of our schedules so crazy here there was not much housekeeping going on...so on hands and knees I have been scrubbing, cleaning, and beating myself up with everyone else here to be ready on Tues!!!
