I am in a situation that I dunno how to manage..
I have a woman who addresses me nice words, at the beginning she asked me out and I said "no" or I told her that we'll do that at another time.
After some time I agreed to accept to enjoy her company

She is telling me that I am sweet, she seeks to be in contact with me, we talk a lot on the phone, etc. However, when I am getting closer she reminds me that we are only friends.
So, we have this:
- she likes me
- she doesnt want to be with me sexually
- she do not want to have a relationship with me
- still, she is trying to seduce me, her nonverbal is seductive
I feel good with her but it is difficult for me to "read her mind", I dunno what she wants. It is clear that she is playing some kind of game but... why is she so much in contact with me? She invited me to her place at some point. She sends me SMS telling me that I am in her mind and senses, etc. Strange..
Does this look like a simple friendship to you?
She is 4 years older than me. Starting from the beginning of our "relationship" she told me that she likes me, that I am sweet, if I am not calling her she will call. She is telling me that it is not OK to be together because we are working together but still, she loves to compliment me and be in contact with me. Verbally she is telling me that we should be only friends but her nonverbal is telling me something else.
I am invited to her place in a few hours and I dunno what to do next. I am thinking to confront her. I feel that she wants me but there is something that stops her to accept it. What do you suggest?
