I am not in your position but I'd put my daughter first.

I would explain to her that he is their to show support not to replace her dad. And that soon enough she will move out and you need to be happy and content to. My kids are 9-11and 17 and they are all happy for me to move on and be happy. I think it is all how you present it. also make a good point to her is their are no step- kids involved so much more chance of her getting spoiled with love if this works out

Until there is a ring on your finger and a date has been set do NOT involve your dating with your teenage children, it is not necessary.

Thank you ALL for your imput. I realize there is a thin line I must walk and not too much information can be shared with my children but while I thank you for your imput Id....I think that is the totally wrong approach to any situation involving children. My children were blind sited by my ex's affair (as was I).....I am going to be up front and honest with them about whom I keep company with. I believe that mom of three's advise was more in line with my thinking. BTW, I have a suspision that my ex's relationship with the "other woman" is going poorly and he may be putting ideas into my daughter's head. She has always been daddy's girl.

Again...thank you ALL for your imput!
