I know....you've already heard it a million times...
You are better off without him.
You are missing what you
thought he was...not what he actually is.
Get out of the house proceedings now, if possible, unless it's a place you really love and would want to be in no matter what. In that case, get
him out of the house proceedings.
Understand that you will be sad for a while, but time will heal....
Think about the relationship...and I mean really
think...and learn the lessons it is supposed to teach you.
May I respectfully say that this statement that you made:
"this man has been my whole world for the last 2 years...he is the first thing I think of the second I opened my eyes and the last thing I thought of before I fell asleep to dream about him"
needs some careful consideration on your part. It's never good to make someone your whole world, as you are finding out. Because when soemone is your whole world, and then they are gone, you have a whole world, instead of part of a world, to rebuild. And yes, I learned that from experience.
So, here's what you do. You work on
you. You work on finding interests, hobbies, friends....things that you like, that you are attracted to, that you have always wanted to do, and you DO THEM! You build your life, and then when the man who is supposed to be in it arrives, you will have a life to share with him.

I really remember how hard this was.
