I'm a girl but I asked a guy this and he said ''A girl who ain't afarid to be herself and will stay with me no matter what.''
Some guys want to use the girls, but some like to play it low and really get to know them. Most guys want looks rather than personality. Good luck! <3
Guys vary, I personally like girls who are intelligent, emotional, stable and committed in a relationship. Someone who can believe in her guy no matter what. Someone not too money conscious what I mean is mad about money and some one independent.
How about trying to running background check on the girl you are particularly interested in and work on that, good luck.
