Hi Nick, you sound like a super responsible nice guy. Sounds like your marriage is based on her moods. If you keep forgiving your wife for infidelities as well. She knows she can get away with it but if you keep on doing it, you might have to start taking DNA tests to make sure you are the baby's daddy. The main concern here though is your son. You need to make sure he is safe. If it were me, I would not take my eyes off of him. And she is letting virtual strangers around the baby. I mean who knows what these guys could be doing...drinking and driving, drugs, swapping STD's. I know it has been a real roller coaster ride but that's what untreated bipolar feels like and she's been taking you and your son along for the ride. Your wife wasn't prepared to become a wife and a mother. Even if you attempted marriage counseling, she would most likely need one on one therapy for a while before a counselor would agree to see you together. I am not even a mother and I am worried sick about your son. He needs you!
