Fiance break up. Im broken

My fiance and I got in a fight yesterday. We didnt talk for like 40hrs.

Today I was ready to talk and figure things out,and he came home,got a few things and said hes sleeping over at his dads(2hrs away)...

I got super mad and told him if he leaves,Im packing my things.

He stopped. We had a few words. Then he left. He waited outside in his car for 30min.

Then he left.

And I dont blame him.

I thought we were gonna last forever. I never thought Id ever feel this sickening feeling of heartbreak ever again. :,(
