I've over this date! I'm thinking of leaving to hit the gym.
What's wrong with you! Why are you thinking of ditching her?
First of all I have been told that guys have it easier if they would workout to pick up girls. Second, I'm bored as hell and this date just keeps dragging on as the girl just tells me stories about things I got no care to listen to.
You have a lot of valid reasons to leave the date, but it's insanely rude to have done so mid-way. You need to give her a chance and just not go for a second date instead of abandoning her. If it really wasn't a good idea you should have told her in advance.
She was so boring. I'm glad I left.
That was pretty inconsiderate to do to her. Once you get a reputation for doing that, it'll be hard for you to find another date.
