Dreamed that my ex still wants to be with me?😧

i was together with him in 2013, but now im married to my man and of course moved on... he treated me bad , thats why i broke up with my ex.... we were friends back in junior high years.... in high school we would share lockers and go to parties ... He was a nice guy tilll we became a couple my senior year in high school:... It started to be bad and i regret til this day that i got together with him... He basically wanted sex from me... thats what I thought.... It was better when we were best friends in high school... anyways now i been dreaming about him and i dont know why....He has a girlfriend already.. Not that I don't want to be with him... How do i stop dreaming about him?? Does this mean he's thinking about me? i heard if yu dream about someone they are ... ? .. but the dreams are good not bad... i just hate dreaming about him😡😡
