Custody of children

Husband having an affair with his wife's niece

Q: My husband, 36, has been having an affair with my niece, 20, for the past few years. Everytime I confronted him he denied it and twists it around like I'm crazy and insecure. However yesterday I caught them redhanded in each others arms kissing, etc. What is the position of my nikah with him? We have 2 sons aged 16 & 14 and a daughter 11. My concern is custody of my children, should I choose to divorce. Please advice me of the way forward.
