I talked with an unknown girl yesterday, I kindly asked her for her phone twice. She denied, claiming that she doesn't give away her phone number easily. However, she gave me her Skype id. Is this a sign that she is not interested in me?
It isn't a sign of disinterest. Its a sign of being cautious. I wouldn't give a random guy my phone number either. I'd need know him a little more before I'd give out my number. I'd only give him it when I felt comfortable to do so. It's naive to give out personal info to people you don't know.
She gave you her Skype I. D , thats good. I guess he is just saying that she needs to get to know you more before she hands out her number. I am like that so I kno but I still give people my facebook, etc.
she gave you her Skype which means that she wants to keep talking to u but since your a stranger you dont have much of her trust yet and giving you her phone number is quite private id say she's interested though
