This is a delicate one so I am taking my time through the evening to think on it.
I am sure you can slip the idea of kids into the meeting subtely so she knows you are supportive of the idea...
IF she does attack you as a bad father you can just say :
The men you were chasing after weren't exactly setting a stirling example of the maturity that's necessary for fatherhood now were they?
What I am doing NOW is what a father should do :
a. Protect his home b. Protect his marriage c. Make civil, cooperative, adult choices when things are at their worst. d. Kids need someone who will be an adult when a house is on fire... They don't need some creep pouring gasonline on it in secret.
The prospective fathers you were chasing weren't any better : one was already married and the other was flaunting using you sexually to me like a sexual predator. Not model father material now were they?
Having children doesn't mean you are a good parent. It just means you were blessed. People spit on that every day.
Stuff like that... that's IF she challenges you on being a model father.
I will work on some ideas of how to sneak a willingness to have kids into conversation later tonight.
