Relationship

Can a couple remain as friends after they broke up?
This was the question asked in the show - Dear, Dear son-in-law
Pierre Pang in the show answered, "if a couple can remain as gd friends after breakup, there's only 2 possibilities.
One - they never truly love each other before.
Two - one of the party is committing silently for another.

What's ur point of view? I don't have the answer myself.

One of my friend posed me a question today.
He asked, "should i let pw (his gf) to become an air stewardess?"
I said, "why not?"
He answered, "because i have a few friends, whom allowed their gf to work as an air stewardess, but they nv ended together, the reason was they seldom meet each other and their gf changes to another person."
I said, "let it be a test for both of you"
but he says, "but i know i can prevent it now so why shall i let it happen?"

I was dumb-founded at the moment.
He said, "can i be selfish for this one time?"

phew~ relationship is really easy to start and hard to maintain huh?
