Go for what? No way, this girl is loose and although she may spend time with you, believe me it will not only be you. Please do not reveal your feelings because she will use it as power over you. Your time together has been rather iffy at most. I am not saying that you should not try to date her, but I would not reveal my feelings until she shows that she wants to be with you and only you. Listen to what your friends have told you. BE CAREFUL!!!!
Just because you reveal your feelings to this young lady means that she will come running to you, sometimes it pushes people away. Please think long and hard before you do this. She does not seem to want to be in a relationship, but she does want to keep you on a string and I see you are still dangling on that string. Do not be afraid to date other women, you may be surprised.
