Am I infatuated or more?

Sense 2005 I had feelings for a friend. She lived like 100 miles away so I really never go to talk to her about it. We talked on the phone sometimes but I would never bring something like that up on the phone. It got to the point where I had to pretend she didn’t exist so I could get on with my life. She hadn’t noticed and figured I just had stuff going on I guess. On St Patrick’s day 2007 she was at my friends party. I wanted to talk to her about it but I knew she was not staying in the area long so felt it would not be wise. We talked on the phone a few times but again I had to walk away. In December of last year we reunited and hung out a few times. And again I started feeling for her. Can Infatuation last that long, or am I truly in love? The thing is the most physical contact Ive ever had with her was just hand shakes and hugs until December.. So I don’t really think its about sex.. yes i am attracted to her that way but my feelings seem much more pure. I don’t want to have to stop talking to her again over this.
