so theres this girl i like! iv liked her for a while and she said she like me to a friend but i never texted her or spoke to her because it felt to awkward (she told friend not to tell me! and would be obvious if i spoke to her), anyway since then she must have started talking to another guy and left me kinda gutted! but she has stopped now because she was putting on fb thats he lied to her ... ( this was like a week or so ago?)

now i have a chance to start texting/talking to her what should i do?
should i like her profile picture to show that i like her or just message her ?
