hey IBM, i think you slowly have to change your ways around her. Eye contact is huge!!! Through out the day try get some eye contact happening, if you get her looking back, thats an awesome start. Then slowly slowly start to chat to her, you could just start with her how was the weekend blah blha blah. Try loosin up, believe me you can get her if you want. Also make sure your well groomed in all ways, dress well, wear a nice cologn... Goodluck and keep us updated
p.s if you have started to think you could live with girl, then you have to force your self to make an effort around her, even if you sh*t yourself, you got to do it.... you will be amazed...
