Dad or Step-Dad, who should take daughter to YMCA Princess?

i understand your point of view and i must say i admire your loyalty to all of your children. I see your point about she may feel left out. I think you should let the dad have this time with her, but i think you should tell her that. tell her you really wanted to do this with her, but her father does too. and you feel like you should give him the chance. see what she thinks. she may be cool with it or she may tell you she wants to do it with you. she is a person too, just because she is your child doesnt mean you cant be upfront and honest with her.
