Is this why some girls do not like nice guys?

Because being a "nice guy" isn't the end all be all to being a good man to be in a relationship with.

I've been with plenty of nice guys who would do anything for me. Many of them were also obsessive and more emotionally needy than I was. Having to sit through the grueling emotional dishouts that many nice guys have given me in regards to why they are so emotionally damaged and afraid of having their love rejected - my friend, we have been together for two weeks.

Call me cold and callous, but many nice guys that I have been with are overly insecure, needy and clingy and there's no room for that in an adult relationship. I don't go for jerks, my current is a very nice guy who too has been left for being a nice guy. Many women enjoy rejection and have Daddy issues and continue the cycle by picking jerks to father their children and it's a damned shame. The fact remains though, there is so much more to finding the right man than being a nice guy.
