the problem is I don't have very much time to talk to her during therapy and she comes with that guy that even though she told me they were just friends I don't know how he feels, I was thinking of slipping her a note saying:
Hey Anna,
We don't get any time to talk but I would really like to get to know you and see if you are as interesting as you seem ;). Here is my cell #, if you text me your # I will call you. If nothing else comes out of it at least I'll have a new friend in Detroit which is one more than I have now! lol
Should I write this message to her?? If so is this what I should say? What should I add or take out?
I'll be straight up and say this girl isn't the hottest woman I've ever seen (although she is fine as ****!) but she's got me. Something about her reaches deeper than any other girl has in 6 years and I at least want a real shot with this one...

Be a man and talk to her. Little notes are for little boys.

or introduce yourself to her friend and ask him if she's single.This will let both of them know your intrested in her.If he's just a friend he is going to want to know your intentions anyways

I wouldn't write her a note if I could find the time to talk to her alone.

Dont write her a note it could creep her out

What are you afraid of. Go up start up a conversation than ask her out.
The worst thing that can happen is you get shot down. You'll live.

Definitely no note. You need to show confidence to her. That note will not do it.
"Something about her reaches deeper than any other girl has in 6 years..."
You are building her up too much in your mind and making this more difficult than it should be. How would you ask a guy you just met to do something? Think that as it will help you get over your mind game. After you talk more if you still like her start the fuse to the fireworks.

No note, just talk to her
