I expected no other reply than that. That's fine, however you want to justify it.
The one thing that bugs me, and what I was trying to point out, is that you have this sense that if you aren't hanging around her that she'll move on to someone else. She might. Or she might even if you are available and supportive. However you justify it, you are hanging on, waiting for her to notice you. Do you think that maybe after a year of this that if she was going to notice you that she would have already? I think it is probably unattractive to her to be so obviously hung up on her.
I knew this guy that was infatuated with a girl that was his friend. They did things together. He was supportive, much like you are, including financially supportive. They went to the bar together and hung out. I talked to this guy and he felt if he was just there for her that she would eventually realize what a good guy he is and they would have a chance. I felt bad for him because she had said that he was only a friend and she wasn't interested in anything more with him. He never did get together with her. She accepted his support and all that, but nothing came of it. Perhaps you should clarify...."where do you see this relationship going?" or "what does this mean to you, if anything?"
