I have been having affair with my elder brother's wife for five years now should I tell my brother man cry out

 

I'm 27 years old guy and I have been having affair with my brother's wife for about five years now. They have been married for ten years and they only have one son who happens to be mine.

My brother is a business man and he travels a lot, he's wife is very beautiful and I've always been attracted to her. We started seeing each other and we even have a son together, my brother thinks my son is his.

For the past five years, I have managed to control my anger and jealousy but I'm tired now. I can't stand to see the woman I love with my brother, I want my son and my woman to be with me and I'm planning on telling my brother about this.

I feel bad that I have to tell my brother because he has always been like a father to me, he's the one who took me to school and even got me a job but I can't keep sacrificing my happiness for his sake.

 How can I tell him this in a gentle manner?...... Pls drop comments under this post for him to see he need our advice
