I really need an idea for a novel?

please none of those 'you need to think of your own idea' answers. i really need an idea for a novel. i like to write dramas and romances. but i usually lose interest in my stories. im really frustrated because all my stories slip into the same cheesy cliche and i find that my stories aren't convincing enough. i want to write something besides the whole boy meets girl thing. i enjoy writing about family dramas, couple dramas, combination of the both. i also enjoy writing in the forties, fifties, sixties and seventies..maybe also something like Atonement too, like England in the thirties.. any ideas? thanks
