Have you ever gone out with a guy whose approach was less than stunning?

It seems everytime I make a little mistake here and there with a girl, that's usually the end of it. I called her two days in a row (doh!), I tell her too much about myself (dammit!), i text her to ask if it's okay to call her (weak weak weak), e.t.c, things like these have often been the end of many potential relationships that had a good start. It seems almost as if the guy has to has his game pretty much perfect to get a girl. Is this really the case or has this just been my experience? Share your thoughts.
