This is crazy. You are going to be the only one who can figure out if she likes you or not.
Its really not that hard to tell if a girl likes you or not, if you are paying the slight bit of attention. Take her somewhere. Once you are on your "date" or "friends night out" flirt with her, if she flirts back, then consider taking it to the next level. If she is not interested, you will probably find out pretty quickly at this point.
Now what's the garbage about having no need for female friends?
Are you nuts?
What do you think a lady you end up dating will think, when she finds out you don't have any female friends? She is going to think you don't really like women, or the company of women. I am friends with lots of woman. They are always trying to set me up with other girls they know. One of them has even made it her mission to get me marrried. She introduces me to countless women. I have no interest in getting married, but sure don't mind meeting them. I couldn't imagine not having female friends.
