Am I doing the right thing ignoring her?

So there is this girl we text each other a fair amount, about 5 times a week for about 4 hours at a time, I am always the one who texts her first though. I like her and I told her this last November, she said she couldn't see herself being with anyone at the moment and that she wasn't sure she liked me back. I thought I'd give her time. We are actually currently in different towns because I'm away at school but I seen her over christmas and she is suppose to be visiting where I'm to in February because she has a fair amount of friends here. I'm starting to feel as if she isn't going to come around and that she just is never ever going to be interested in me. Someone suggested to me to just ignore her completely to help get over her. It had been 5 days and yesterday she texted and said "hey sup?" I ignored her. She sent me a message on msn that said "hey?", I ignored her. A few hours later she sent me another text that said " hey haven't heard for you in awhile, texted you got no reply, sent a msn message got no reply, is everything ok?", I once again ignored her. My question is that do you think I'm doing the right thing is ignoring her? Think that maybe she actually likes me now and that is why she is texting me? What should I do?
