Why is my Dad addicted to me?

Dont get me wrong but my dad is literally addicted to me. He is this 6ft tall man that brings himself to tears when he thinks about me leaving or moving out. He is literally addicted to me. <br><br>He dosent want me to go to uni because he is afraid I'll leave him. He doesn't let me go out on the weekends because he is afraid "that I'll go and never come back". <br><br>I've tried to reassure him that i'll never leave him but then he said to me that he is addicted to me and that he cannot stop thinking about me. He loves me but he said that he is scared that I'll wake up one day and I'll leave him. <br><br>What, is he going to have a mental breakdown when I get married and move out? He's literally crying about it. What do I do?
