Do you believe this man is good to your son?
Thank you for answering my questions. I can certainly understand your concern. Your son will probably feel even more lost is the family if they have a child. It is wonderful that you can be there for him 60% of the time to give him the special attention that only a father can provide. My advice would be that you, your wife and her husband-to- be meet a few times with a Marriage and Family Therapist to discuss parenting issues regarding your son. I know this will be difficult since you and your ex are at odds, but when a child essentially has 3 parents, it is very important for the them to have and civil relationship and good communication as this make the child feel secure. I would find a therapist first and then talk with them about it. Would you like me to recommend someone for you?
