I'm going to give you a differing opinion. It sounds to me that because you feel the need to tell her anything that you have strong feelings for her. The problem is she doesn't seem to have feelings for you.
If it were me, and it's not, I would cease all contact with her and let her make the next move. You're trying too hard for someone who doesn't appreciate it. If you are to ever have a realtionship whether girlfriend/boyfriend or just friends, it's going to take both of you. If she's not involved it's just you obsesing.
Again, just me, but I'd wouldn't do anything. Don't call, don't answer her calls or e-mails. If you do this something interesting will happen. Either she'll contact you wondering where and how you are OR you'll have moved on and you won't care.
But that's me.
