lifesaver, never change. I don't buy that whole "Nice Guys Finish Last " theory at all. If a guy is nice he finishes first in my book. I mean true some girls are just drawn to those guys who treat them like crap and they never learn or they learn to late,but not every female is like that.
Alot of times, guys start out being nice and then they turn into total jerks, so either we didn't get to see their "true" sides in the beginning or we were blinded by umm "love". ( This isn't just guys, us girls are like this too)
I think the whole being upfront, honest, sincere and forgetting all the games and nonsense "snags the filly", because A. She knows your there, B. She knows your thoughts on the situation C. It's more comfortable to get involed with someone who can be expressive and upfront in the beginnig, then playing the guessing game and trying to figure out whether they will be cool or turn into a jerk later on.
Be yourself, don't change your ways to suit the stereotype, be the suave nice guy we all know here on GC and I am sure things will work out .
Good Luck " Snagging the Filly"
