(e) She promised that she will take care of the dog forever.

She promised that she would take care of the dog forever.

Of course, neither humans nor dogs live "for ever", so she could not possibly keep the promise!

Thanks.

What about the expression "I'll love you forever."

Take me.

But will you love me long time?

Of course it is is a kind of poetic exaggeration. There is probably a Greek name for it. I did not mean that the expression was ungrammatical.

I think "I love you forever" means "I love you till death takes me away from you."

Try googling the answers or studying an on-line grammar textbook such as:
