Promises / Dream = ?

Once apon a time..a friend told me that he's worrying his outgoing girlfriend..

He said that," what to do? I will just let go if she find another guy as a new boyfriend."

What I've been told was make my mind think alot,

If there's no responsibilties for him to retain the relationship, means that's not love.

If there's no love,  why still stay together?

What I told him is, our action may change the situation, and everything.

After a year, he's proven this to me, both of them live happily.
Recently, he find me again.
His lovely girlfriend is look forward to have a air-stewardess career,
She hopes to travel around the world...

"Promises are fake, she promise to travel with me but not with career."

"I couldn't change her mind,  she'll pass the interview for sure, with good appreance."

I can see his suffer, by the quantities of beer bottle on the table.

"Don't worry, all will be fine unleast u tried hard, with your sincere mind and heart, if she doesn't knew that, I knew.", I try to make joke.

Finally, he replied me with a smile.

We went back with a "relax-ed" mind.

That night, I was thinking of her,

Bad things...Good things...and all the Memories...

Thinking of  the quotient of PROMISES devided by DREAM,

The denominator should be DREAMS...or should be PROMISES?

Lastly, I think get the answer is ERROR, LoLx.

My Explanation is, there is very difficult to make the choice,

Because, He/She would be your DREAM MAN/DREAM GIRL,

But unfortunately, He/She waould have many DREAMS too.

Accept is the only solution, althought he/she will have a chance meet up another,

Or the career will make distances.

I've been found there's nothing to be regret.

Because of her, I'm here.

I ready to face everything, include the case that my friend's told me.
