I am confused by what is happening, as when i suggest we meet up, she just cuts me off.
its hard to know the reason why, and the first time it could have been for any reason, but its now self evident that she shuts down when you ask her to meet up. i wouldnt do it again.
you know her best. you mention that youve been friends for many years. did the two of you used to get together? was there perhaps a falling out? do either of you have feelings for the other, or is it possible that either of you think the other does?
