We also don't know how old these children are, but that's besides the point. What message is she sending to them as an authority figure?
Don't have children until you are an adult and financially able and willing to do so (since not everyone wants to be married anyway)? Get your education and have a fulfilling career before you bring life into the world? It's not okay to run from your mistake (if this was indeed a mistake)?*
*Again, they wouldn't or shouldn't be privy to this information any doggone way. When I was a teacher, I did not discuss my personal life with my students. Heck, I wouldn't even discuss my age, let alone who I was sexin, how long, or whether we were married. I was their educational/academic and professional mentor and example. I was not the role model for how they should live their entire lives personally.
It's like parents want everyone to do their jobs for them. Teachers, celebrities, and etc can only be so much of an example for children. These figures are not here to raise other people's children for them.
