I am addicted to sex with my biological father!

Hello, I am Monica, I am very jealous of my MUM! I have a really big problem. I am addicted to sex with my biological father. I have tried having sex with other men but it is just impossible. Dad is the best. It all started when I was 17 years old and my mother had left me under the care of my father for a whole week. I used to hear my mother scream joyfully in bed while my father had sex with her and I was always curious what really happened. On that night my father claimed he was lonely and requested me to sleep with him. He was so loving and did not have sex with me on that night. Instead he cuddled me and touched my private parts and licked it really good. The following day I slept with him again and this time he penetrated into me though painful he did it with care and slowly until I could handle it, it all was so sweet that we ended up coming together. That was the best experience I have ever had in my life. After that day I have always had sex with him either twice or once per week when my mother is not at home or we book a lodging in town where we have great sex. Unlike the men I have had sex with, my dad is caring and loving, he always tells me good sweet things before sex and makes me comfortable, after I have come, he licks my “thing” to clean it and holds me closely telling me sweet things until I sleep. Believe me in his arms I feel as though am in heaven. Right now I have cried all night because I heard my dad having sex with my mum am and am so jealous and see my mum as competition at times. I wish I can run away with my father and be with him alone somewhere forever. I need help because I know that is impossible I am 21 now and need to move on but do not know how to. Kindly HELP!..
