Why can’t I stop thinking about my ex all day, every day?

We been separated for sometime and he's always in my mind... morning noon night. he's the first thing on my mind in the morning till bed time (even in my dreams)... Its like he lives in my mind... Its too much for me.. I hate it. I try to keep myself busy... Like dating and doing activities with the kids. I did cord cutting so many times, Meditation to clear my mind.. even reiki. I talk to therapist because I feel like im crazy. I never thought of anyone like this before. I pray to God to get him off my mind. Have anyone experience this and why is this happening to me?
