cause granny said so

"if your husband turned cold like a rock, you can't do anything about it."

early this morning just when i'm about to take a bath my grandmother started saying things about relationships and its bitter ends. she said if a man's love for his wife slowly diminishes as time goes by, and if the time will come when the man feels nothing special for his wife anymore, the woman can't do anything about it. no matter how much she love the guy, she can't anymore bring out the passion they once had. granny even reminisced the past and of those her friends' relationships which ended up cold and bitter.

that made me think: why is it to be that way? why can't they just love each other till the end? cause how can they even muster to say those vows when they can't stand it in the long run?

but you know, i have no accounts on saying these things or to give consistent opinions cause i haven't in a serious relationship before or even now.

i just wonder why granny said it with much conviction. like she's pretty sure every relationships end up that way.
