'I've fallen for a flirt on a social media site'

Dear Uzair,
You have created an image of this girl in your mind. But chances are that when you meet her she might just be the opposite of what you have imagined her to be. You say she is a flirt but what about you? You are the net Romeo eyeing every single movement of the girl. There is no harm meeting her as she is from the same city. But how can you even think of proposing to her? First you have to befriend her. You cannot go alone by her social media profile. So wait till you meet her in person and then decide the future course of action.
