ya agree, if he fails to keep his promise, he cannot be trusted.
But then again, how many of the guys who have a girlfriend wouldn't
just promise for the sake of stopping the girl from worrying or
just to keep her mouth shut for just 5mins?
What do you do when she says, "dearrrrr, can buy me this diamond
ring?" or other stuffs like bags, clothes when you're not even
earning $$.
What do you do when she says, "dearrrrr, can you bring me to the
moon by tomorrow?" and she keeps bugging you day and night, she
gives you the sad/black face throughout the whole relationship or
threatens to break up with you unless you promise. Because you love
her so much, you agreed. Can you do as you promised? If he can't do
it, the guy = cannot be trusted?
Zarks I don't think you have had a girlfriend. You don't know what
kind of unreasonable things girls can ask you to promise. Don't
talk about girl friends, if your mother ask you to promise as
above, can you honour your words? If you can't, you're useless, you
suck, you cannot be trusted? 
Sorry, this is nothing personal.
