I am not sure if some of you guys are cheap, or trying to make a point; at any rate, not paying for dinner on a date is a MAJOR faux pas! If you are the one planning the evening, then you should be the one paying. The only time it is acceptable to go "Dutch" is when going out as friends!
There is nothing worse than thinking you are being treated to a nice evening out, then being surprised with half the check at the end. This could say one fo the following:
You are cheap.
She doesn't deserve to be treated.
You are not interested...or...
All you are interested in is sex and couldn't care less about getting to know her.
If any of these are the case, then you shouldn't be dating, and when you are ready, make sure you are able and willing to treat her to a nice evening. Doing so will make her feel special and guarantee a second date.
And remember guys...
