I scoured the Internet for advice about dating people with kids. I got the same advice from multiple people: "Be yourself." OK, what next? We were on and off, and it wasn't the healthiest relationship I've ever been in.
The only books I could find were about step-parenting. Considering the divorce rate in this country, I thought finding the advice would be easy. *crickets* My relationship with this man continued for... But I did learn a LOT about the kiddos and how to deal with them.
For now, my advice is to also play the waiting game with the ex -- take your time before you meet him or her. Realize you are taking someone else's child into your life.
Show that you care about the child, and you will go a long way towards a good relationship with the mother or father of your brand new kid.
Honestly, she's still a virgin which is a bit rare for teens (I also teach high school).
