Are you able to answer this honestly?

I have always found the ways people express the power of their
emotions – in regards to a relationship – to be lies. All of this “You are my everything” and “the most important” and “my life” and so on, are obviously not true!

The question is at the end of all this but, first I want you to understand where I’m coming from since I am finding it difficult to believe that I’m crazy in this so, bear with me.

For illustration purposes, here is the scenario:
I’m your significant other and you’ve just told me all of the aforementioned sentiments to which I respond ( In all seriousness) then quit your job, sell your car, and say goodbye to your friends and family.

From experience, lets skip all the reasons why you will not do as I ask including the one that goes “I would never ask you to do that” and the one that
involves the control issue and the one about how wrong it is to ask and – just don’t. Lets skip to the part where I say 100% is simple math!
I mean, this thing, that thing, they all add up so that if you really look at it, take that sofa for example. It cost three hundred so, if you would not give that up for me then we can even come close to assigning your real value of me as, somewhere under
300 dollars! Even this is appalling to you! I am trying to find out exactly what importance I hold since, looking at everything the way I do, it seems apparent that I hold little importance since you’ll only give up the little, less troubling, aspects of life.

Anyways, I’ll spare you the rest of the disaster and get to the heart of the matter and, I hope you are not offended because I am speaking to you. Having said this, the question is:

Why did you lie to me and tell me I was your everything and the most important?
