For your friend's case. We'll just wait and see lor.
As like i've said. A relationship is not complete just by seeing
couple happy. I have seen cases of a couple(both my close friends
but the guy is a player converted by this girl into a good bf)
satisfying one another in many aspects and they looked really
blissful. I've had chances to ask each of them personally how
they've felt being in their relationship, and they were happy.

Lucky guy and girl....until one fine day, they broke up and he
called me up crying away. He didn't understand a single thing he
did wrong.
Something i found out from her. She had a quiet desire for a
adventurous and playful guy. My friend is too 'NICE' to her and she
agreed being happy with him cos he did all she wanted a guy to. But
he lacks something. So she left.
>>>Too too many of such cases, ASk YUnnie and Dev about
it.
He believes in that she had completed him, does it
apply the same to her? How would anyone know other then
herself?
Foundation of relationship, duration of being
together, personality traits, character compatibility, being most
important when looking into a more secured relationship. Social
circle and external factors comes next.
Like in my fourth point, i have already stood on my point.
We can do our best, however we cannot control another party of
emotions and depth of love unless AOS is applied.
And like your friend have said. He believed in 'Some believes in
searching for The One (Active)'
Half of me will bless him, but the other half denies his
point.
His decision in years down the road might become a pattern or
broken relationship might lead him to evolve for better or
worse.
Eg. 2nd gf - the One then changed to the present gf(the One)
Then present gf broke up, 4th gf became the one...he chnged his
mind many times.
Dearest FeowFeow,
For your guy, time will tell. And i really hope he's the One for ya
too!
Cheers
