As a former single mom myself, I was very cautious about who I told my daughter about or whom I told about her- while I'm not all, "Oooh! Pedophiles are peeking through the cracks!" there is a legitimate concern that someone could pretend to love me to get to my daughter... sad though that is for everyone involved.

I'd say keep seeing her, and ask her what she thinks is a reasonable point for you to meet her child and how. If she says RIGHTNOWOMGLETSGO... eep. If she says something like, "Maybe you can come over for a dinner when we get to know each other better," that's pretty normal. Anything low key (remember, 2.5 year olds are a bit noisy, smelly, and rammy by their nature, so maximize the comfort level) is fine- just try to remember that the kid's not going to be interested in you for a while since, as my darling husband put it, "You're the one who takes Mommy away."
