feeling so depressed

So my bf and I ended things two months ago after five years things were just rough for us
How ever we spoke often in these two months 
So today we had a huge fight and he tells me he was going to take me away for Christmas and was going to propose 
I told him that it would have been my dream but at the same time I was so hurt and angry that now  he tells me when it's over and he said again it's over that I was nasty back and told him he is lucky he didn't cause he is better of without me 
Because of the way we have been fighting he found fault with me so much 
Am I wrong to. Be sad 
Do I say sorry for upsetting him with what I said ?? He got super mad at my comment
