I totally believe this. I think it is obvious, I just second guess my ability to interpret obvious signs. I don't trust that I see them clearly. I am suspicious of my tendency to see things the way I want to see them.
She responds positively when I tell her she is beautiful.
We spend time together alone. (Dinner, movies, hiking, walking shopping)
She remembers things that I like, and goes out of her way to share them.
She openly tells me about things she doesn't share with her other friends.
(I've noticed she withholds information from other people that she has previously shared with me)
She talks about negative feelings she has about other people with me.
She referred to me as "love" yesterday. (Oops?)
Am I looking for something more obvious? I don't think she would flat out tell me, as she has mentioned a few times her fear of rejection.
