Really Would Like Some Relationship Advise. G/F wants more..
She sounds like she is either delusional or controlling. Or both. She will eventually try to guilt or trick you into having the kids you don't want and doesn't respect this choice you have made. The fact she won't even talk about what happens when you still won't is very telling to me. She won't break up with you because she believes in time she can force you to change. My advice would be for you to break up with her so you can both find someone better suited to the future you need.
Doubtful there is such a thing as a right answer here.
Unless the situation is such that your time spent together is not enjoyable, then I might just let it roll for awhile and see what develops. You are both young, and have only been dating for 7 months. I once dated someone where there were possibilities for a long-term relationship, but still questions. I allowed it a year for things to develop before calling it quits so that we each could move on. Either way it seems a great opportunity for a learning experience in dating.
Under the circumstances one thing to indeed watch out for is:
Codependence is not a joking matter. I might watch out for someone viewing me as their pet project. Her interest in your personal growth seems a bit limited to where that growth is in the direction she wants, e.g. you becoming her corralled breeding bull. Careful that any wedding ring doesn't wind up through your nose instead of on your finger. (Forgive the colorful hyperbole - I've had too much coffee
