Dream Of Getting Engaged With Brian

I was helping set up for a party, the apartment was small and happened to belong to someone I am friends with and on occasion sleeping with in real life his name is Brian. During the party something kept keeping me in the bathroom Showering, washing my hair, pooping, a friend inhad never i did not recognize kept coming in and forgetting our drinks and when she remembered it would be the wrong drink. Some how I ended up leaving I think to run an errand. When I returned the party was very loud and was packed outside I sat on the porch listened to music and i think some fireworks were let off. When the smoke cleared I saw Brian and ran into his arms. In real life when we go a long time without seeing eachother I always greet him by jumping into his arms wrapping my legs around his waist and kissing him all over his face and cheeks as I giggle. I did this exact thing in the dream. He held me tight as we both giggled. We ended up falling to the ground and started laughing. As we laughed we were talkong to eaching other I could not make out what we were saying because the music was so loud and the fireworks were going off as the smoke cleared I heard him say marry me and something about not having babies. The music started to fade away and I said "what"? He repeated what he said. I laughed and said what? He repeated it again. I looked at him smiling still in disbelief. He explained that he promised to give me a baby before as a sperm donor, but now he wanted to marry me with no promise of babies but if they come we'll have them. I stopped smiling as I processed what he said I looked at him and he was serious. I said in a low tone "oh my god" and got off of him. I stayed sitting on the ground trying to catch my breath i was still in disbelief. I looked at him to see if he was kidding, his face was serious. He asked "well?". I realized he was not kidding and was being serious. I gave a little smile and said "ask me properly". He smiled got to his knees pushed and got me to my knees and held both of my hands he started saying something I couldn't hear what he was saying all I could hear were my sobs as I cried from happiness. He finished speaking and we stood up and I said with tears in my eyes and a big smile on my face "yes I'll marry you!" I jumped in his arms and started kissing him. He said wait reached in his pocket and pulled out a ring it was not a diamond but a bright pink firefly or butterfly. Someone pointed out that it wasn't a diamond I smiled and said it's perfect. Out of excitement and confusion he put it on the wrong hand I started laughing took it off and put it on the correct hand. As we held each other the picture started to fade. I realized i was starting to wake up dream me and sleeping me said no and tried to hold on. Real me started saying no please no, don't let it be a dream I kept my eyes shut tight but the picture faded away. I opened my eyes and all the happiness i felt was gone. I have been sad in bed ever since i woke up. He is not my boyfriend but we have been friends for over a decade and have been intimate on and off over the years.
