How old are you? I didn't understand anything at all and nobody can help you if you are this unclear.

here's what I got from the story:
you've been friends with this gal for 5 years. In the past 2 months she has started pushing you away. She says the reason for this is because you invaded her space. You agree that you have invaded her space but you don't think that's the only reason that she's been acting this way.
if you are truly sorry that you have invaded her space then apologize to her. And remember: and "im sorry" is not just to make someone feel better. And "im sorry"= "i will try my best to make sure that it never happens again." unless you mean it, then don't say it.
if you think there could be another reason besides invading her space, then ask her. The only way you can get the real answer is to just flat out ask her.
so apologize, ask her if there's another reason why she is acting this way, and suggest that you two be friends again. That's the best I got from what I could understand.

Back up, and stop invading her space.
