You woke up to crying.

You looked at Tony and saw he was crying in his sleep. He was whispering "no" over and over again. You knew it was a nightmare and woke him up. He hugged you tightly and said "your alive but what about the others". 

You told him it was just a nightmare and he would feel better after talking about. He agreed to tell you about it. 

The Dream (Tony p.o.v) : 

I looked around and saw my friends in front of me dying. There was nothing I could do. Peter said "I love you dad" before dying. Steve said "you could have done better" then died. I walked over to y/n and saw the ring on her finger. We had been married. She said "you did this honey, you are the reason we're dead, but I still love you" then she and the rest were gone too. All I felt was sadness and pain and the next thing I knew I was crying. 

When he finished telling you that you were shocked. You pulled him into a hug and said "that will never happen" 

He said "I love you y/n"

"I love you too Tony"
