Your post was all over the place and confusing, maybe you can explain it to me a little more?
Have the two of you been intimate?
How does she feel about how you feel? You told her how you feel?
Why did you say you're working on the internet to make money?
How do you know that light means someone is there? Why are you checking on what she's told you?
What is your question?
We can never know what's in the heart and mind of another person, unless they tell us, and even then we have to trust that they are telling us the truth which may not always be the case. You can ask her straight out if she thinks there can ever be anything between the two of you or you can tell her how you feel, but if she won't reciprocate, either in answering or how she feels, there's not really much you can do about it but be patient and see if her actions toward you change. If she's a good friend to you, then she should want to tell you how she feels so that the friendship can continue, or she might be afraid to tell you if she doesn't feel the same way, thinking it might ruin the friendship you do have. I welcome your thoughts, let me know if you want to talk more.
