Getting Deep! .... in my dreams?

Ok I’m going to start this off by saying I’m in a very happy relationship (engaged) marrying in May ... two beautiful girls 8 n 3 ... but my dreams are making me think WTF 🤔... at least once a week I dream about my EX and when I say EX I mean so far back I was 14 we dated for 2 years and it ended very bad he became very physically abusive and actually tried to run my over with his car and choked me up against his wall where I left him after this ... we didn’t speak for 3 years after where we ran into each other at a party (yes we had sex) I was about 19 at this time it was a one night stand and I to this day never even spoken to this man since even dated afterwards and have been with the man im with now for the last 6 years... so to the point ! I continuously dream about him at least once a week I never think about him ever ! My day goes on but my night consists of him and only dream of him alllll night long I’ll even wake up thinking wtf! And fall back to sleep only to continue the dream on a diff level how do I get it to stop and why is it so constant we live in two diff states I haven’t seen him since I was 19 I’m now 28 ... I know dreams are subconscious and deep thinking but in all honesty there’s nothing there it was a childhood crush first date we never even had sex until that second run in when I was 19 so not being my first... my first time is the man I’m with now... 🤷‍♂️
