Astrologically
speaking, you could have very strong karmic bonds that prevent your
advancement in life. Imagine 9 freaking years repeating the same
kind of love cosmic lesson in life - this is terrible.
Both of you are probably people who encounter problems in that
relationship, but doesn't really know how to handle them OR
avoidance is a common practice. (Unless right in the beginning,
this relationship isn't meant to be - meaning, it was born from
poor ground) It is like there seemed to be meaning in a
relationship to blossom, but as you both got closer, you discover
the oasis is merely a mirage. The reality of relationship sinks in;
either one of you back out - the whole cards of relationship
tumbles.
Years of searching around - still this emotions isn't address. It
hides like a crafty cockroach. It lurks and surface whenever
possible relationship issues were encountered by both you and her
and create much vaccum, which directly trigger her/your intention
to have that contact and return to that state again.
Please understand
that every relationship has their reason for existence and reason
for non-existence.
Basically you have a choice - you can opt for a relationship with
her, but I need to have a clearer picture on your past relationship
with her. More details, the better - so that I could analysis and
give you a complete neutral point of view.
OR
Learn that this relationship wasn't meant to be. You both reject
the lesson of moving forward and love, which history ultimately
send you both walking around the bushes and ended up in the same
location many years back. If you cannot control emotions - don't
land in situations that you know emotions will overwhelm you. Cut
and destroy connections - it hurts, no doubt, not because you
really like her or what - but because the result of your
actions already sunk so deep and the pain of pulling them out
forever is incredibly excruciating.
You could leave the knife there - but you will die by the wounds
eventually. Either one of you are indecisive - please note that
this is probably one of the main cause of today's circumstances.
Gain wisdom, gain enlightenment, embrace your lessons in love.

Cheers
