Dream About Ex Boy Best Friend

i once had a dream about my ex boy best friend. We don’t talk anymore because they cut me off after getting a girlfriend and shit talked me way after, while telling ky other friend to take care of me because he couldnt. Anyways, i used to be obsessively in love with him, so i had this dream that we were together in a way, not officially but still. He left that girl for me, he chose me, and we were hugging and kissing and it all felt so real that when i woke up i started searching for him through my chats, and when i realized it wasnt real i felt a feeling in my chest, that felt like my heart was breaking and i wanted to cry. What does this dream mean.
