Seperation involving kids

Just need advice on my rights with my kids. Me and my wife have seperated and no papers signed yet. Been only 2 weeks, and ive found out she has had sexual relations with her roommates a married couple for 3 nights now. My kids live with them. Any advice or questions please respond. I do want to confront my wife soon. Its tearing me up, mainly cause of my kids are there. Thank you.

Do you have a specific question that relates to your current situation? If she is not allowing you to see the children, or believe it is not in their best interest to stay with her under these circumstances, you will need to file for child custody.
