Have you wondered why on earth did you fall for him/her among
the thousands of people that you could have met on the street? Or
why on Earth did you fell for this jerk/biatch that you knew you
will be hurt ultimately in the end? 
Love and Reincarnation works closely
hand-in-hand.
In astrology, the number of Saturn aspects between couples signify
the degree and number of times the couple have their fate
significiantly brush across. Some of these bonds are fruits of
their good relationships in past times brought over this lifetime -
thus harmonious and blessed relationship is granted. 
While many others have difficult conflict, trials, test that they
have to go through before they are enlightened to a point where
'destruction of past behavior before crystalisation of good ones
can come in.' 
Christian believed that reincarnation is a myth not a fact - then
why are you borned into this particular family, falling in love
with that particular guy/girl, ended in marriage with (possible
another) that particular him/her? The karmic bonds that instill in
your immediate relatives are strong and unescapable. Some have good
families/love relationship, while others have hellhole. These are
debts to be paid or receive from the past. If recarnation doesn't
exist - everyone in this world should be equal-standing family
influence & love relationship. When first badge of human arrive
into this world - probably this can take place (after countless
recarnation, this no longer exist) 
Love works way differently from that of the mind - everyone have
their own destiny when it comes to their own love relationship: the
events that will take place, the people they will meet, etc.

Understand and realise that behavior in every relationship
is different. And criticial flaws that you have to
overcome this lifetime - if it isn't improved or change - chances
are: it will likely to affect you next relationship again. This is
a classic example of people losing a relationship and failling to
learn the lesson behind it. 
People may understand their partners very well - but I seldom see
anyone understanding their own relationship. Let me stress that
Love cosmic lesson stated that not every relationship is
marriage-and-happily-ever-after kind. Even those that are not,
they are there for a reasons and marriage too
isn't always forever (The Ninth law of Love states that Marriage is
not forever.) 
Sign for Karmic relationship: Strong magnetic
attraction - includes love at first sight, losing-me-into-you,
dreams, etc.
P.S: Paying debts from past life sounded ridiculous? Ask those
people who have been through countless of breaking-patching from
the same gf/bf, even though repeated reinforcing has been advised
from friends, family, etc to leave him/her - that poor soul
couldn't and wouldn't. Only when the debts are fully paid - he/she
will be enlightened and leave automatically.
