Seeking primary / full custody

My wife told me that she wants a seperation and the kids. What are my chances to getting primary / full custody if my wife has several hundred emails & phone calls between her and our kids pediatrician. And she has taken several pictures including topless for this doctor. Wild nights out dancing with men who continuously smacked her butt and pulled her shirt up. And now hundreds of phone calls & text messages between her and our pastor and both of them denying it.

Custody is awarded based on what arrangement will be in the best interests of the children. Any factor that can be shown to have an effect(positive or negative) on the children will be considered and no one factor is determinative.
