When my girlfriend told me about this, I laughed even though it's rather pathetic what happened. I told her the story was too good not to blog, so she posted about it. You can read it here.
Guys, don't be stupid. Tell women when you don't want to be with them any more. Women do the same. Don't play games or use some kind of stupid stunt like this to say “I'm don't think it's working out”. Communicate your feelings with words. These tactics make you look petty and childish but apparently a lot of people are this way.
