Sacrifice in love

I am only thinking aloud here, folks. How much, how far, how long can one actually sacrifce in love?

THE TIME TO STOP SAYING SWEET WORDS TO YOUR LOVER

When should lovers stop calling up each other/sending text to say sweet words?

How true is this?

Is this an actually widely accepted saying "we disagree to agree?" Whichever way, it is so true when related with the word - relationship. I once heard someone say that building a relationship can be linked with having a hair cut. For some (especially the males) that God has blessed with a lot of hairs, dare not leave their hair as long as 7days without visiting a barbing salon for a hair cut. If they must look neat, the hair then must be trimmed constantly. Are you starting to get my point? Oh, yes you do - No, you don't? .......How true is this?
