Make her see you as her lover instead of her friend. If she just sees you as a friend that's all you'll ever be. So you need to turn things around. Stop giving advice or help with her problems because that's what friends do and why she just sees you as a friend. Instead, do what lovers do and that is help her forget her problems. Distract instead of help.

Stop going shopping together and giving opinions on things she's thinking of doing. Friends do that and you want to be her lover. There's often a reason why your friends but you can change it.

Girls often want guys as boyfriends if they see them as attractive. But they just want them as a friend if they don't. So you need to get around this by replacing the things friends do and say. Start replacing the advice and shopping trips with helping her forget her problems and evenings out together.

You should start being romantic by taking her out to restaurants, romantic movies or candle light meals at home. If she was already your girlfriend this is what you would do anyway. This will start making her see you in a romantic way. There's also something else you should do.

You also want to make yourself more attractive to her. If you're more attractive, then she'll see you as boyfriend material. Stay cool around her by not being too impressed with her looks. Other guys do that to her all the time and that pushes her away. By being more laid back she'll want to know why and start chasing you.

Bear in mind women find men who are leaders more attractive. Start making decisions about where to go and so on. Stop asking things like, "where do you want to go tonight".

Now you know how to turn your friend into your girlfriend. So stop doing things that friends do, start doing lovers activities instead and become what women find attractive. So get out there and start turning her into your lover.
