Dream of building, punched

In real life, my ex and I broke up. And I'm one of Jehovah's Witnesses. In my dream, I was at an assembly of Jehovah's Witnesses, in the old building we use to go to years ago and my ex was there and we was still in a relationship. Later, we went home, but it was my old house that I sold and my ex was there too. And he was shirtless like he lived there with my parents and myself. I'm trying chicken wings and fried oreos and he comes to me the get some food and I punched him and he felt real although I know we are broken up outside the dream.
