Crush goes offline when I'm online?

[Fairouz]

Girl body was known as the most complicated machine on earth. Their emotion can simply turn bad from calm sea waves to tsunami. Add on, If she can't control her mood in her menstruation period. Well that's just an example. In your case, a woman or girl does not feel wanna love all the time, sometimes they in another thingy mood like shopping, funny things, funny guys, silly stuff or her own interests. A man of her life was able to make her in mood to love all the time. Just post something good in your Fb. Post hot pics to tell her indirectly that you're attractive. The most important part is ignore her for a moment, girl nowadays does not appreciate clingy and sticky guy. So put yourself some dignity and market.

Based on your statement it's too general dude. I can't predict better than your own self. But for me yes! she doesn't like you or she seems doesn't like you to bother her. Give her some space.
