Single parent dating??

I agree with you. I don't think introducing your children in the relationship so soon is good for them. I think it hurts them if they see a person in their life, then they are gone, then another person etc... I know it is hard for single parents to date and keep their children out of it until the relationship becomes more than just dating. My sister has been a single mother for 10 years. It is a challenge to keep my nosey niece from finding out about her dates. She still does it anyway. My niece has never met any of the people that my sister has dated. I don't know how that works for her, but it works for my niece. You are not over reacting, but you will not be able to tell your friend that what she is doing is potentially going to hurt her daughter. Not unless you know exactly what to say so that it comes across right, and that is always hard. She will probably tell you that it isn't your business and not even realize that you aren't judging her, or calling her a bad parent. People take that kind of interference as an insult, so if you decide to be a good friend, be aware that you might lose your friend. I would pick my words very carefully. Even though you have only good intentions, it could come across that you are judging her and her choices and being a nosey meddler.
