@badijabbour,
Some girls have boundries and fears. It could be because you hugged her, she felt that you may have wanted more next time and her way of still getting to see you but feel safe, was to bring a male friend along.
Alternatively, she wanted to see you and found an excuse as you didn't ask her out and she wanted to see you. He was her way of inviting you out, perhaps she isn't assertive.
Text her and ask her what she is doing on the weekend. When she replies, in a way you feel is in your favour ie) nothing, or free on this day, or something that gives you that hint, ask her if she's free for you to call her and call her there and then.
I agree, this world is crazy, face-book, texting, what happened to old fashioned, women "love" old fashioned
Best wishes.
