Confused to death with this girl?

She probably feels that you are interested in her and are coming on too strong, and is freaked out. She is likely busy as well and has other friends she talks to and not only just you. She also probably feels that you are intruding in on her network of friends. Just remove her from msn and give her space. Once she sees that you have a life of your own she might come around. Just leave it as "hi" and "bye" with her and try making friends at uni. You will forget her in no time. Good luck :)
