What does it mean when you dream about your ex?

I had a dream about my ex who I still live with separate rooms. His cousin was there and some girl that I had seen earlier in the day that I don’t even know. That he was going on a date with her or something like that. His cousin was saying something to me donot remember but I remember feeling crushed that he was starting to see someone else. I’m the one that caused the relationship to end by being given dishonest to him about money. He is the only man that showed me what TRUE LOVE is.
