You are
constantly reinforced with the idea that Love is fleeting and that
any moment when the right condition arrived, it will flee from your
clutches and that all you have invested will vanish.
You spoke little, but from the few words, they have all reinforced
the same ideology that trust is difficult and you are unable to
secure yourself.
In the end, the root of problem is within you - because you are
unstable, you are unable leave the stranded island and place trust
onto the raft that is available.
This insecurity will never go away unless you adopt a more
enlightened mindset rather than one that is so narrow, which
confine you to think that relationship are evanescent and that it
is so ephemeral. You probably want to grasp it and control the
movement of your Love.
Ironically, it will abscond from your grip.
Your mistrust and lack of confidence in general relationship
revealed a deep seated inferiority complex and trashed esteem -
which is so critical to any Leo in the world. You are unable to
shine and that Sun (your ruling planet) is waning because of the
void of higher understanding and enlightenment.
Your fear is imaginary and that if you allow it to
manifest, it will ALWAYS become a self-fulfilling prophesy - which
all relationships are fleeting and that trust cannot be put onto an
investment with such adverse risk. Then you will perpetually see
yourself encumbered with failing relationship, with trust/security
issues all your life. 
Cheers
