RE: "THANK YOU, I AM SORRY, I LOVE YOU" || THE THREE INGREDIENTS THAT STRENGTHENS A RELATIONSHIP

Using the words "Thank You" all the time for every simple thing, makes it lose some of its value when it comes from you, but I argue, even with the value loss, "Thank You" is very powerful! That, and quantity is another form of quality, sometimes.

I've seen "I love you" get outdated in some couple I know. I have faith they won't come to hate each other, your second section reminded me of them.

and finally:

YES! But make sure to be truly wrong when you say it. Saying it while you're right isn't a good thing because it makes the other party presist in their wrong doings!
