Sometimes it simply clicks. I'm excited for you.
Years ago had a patient who had been happily married 60+ years. He adored his wife. Adored her. She was very quiet but had this wonderful smile.
I asked him what the secret to a happy marriage was and I never forgot his answer.
He said: When you've dated for the first 3 months? Keep repeating that over & over. You'll be just fine. He & his wife were just grinning. Many children, grandchildren & great grandchildren later.
Listen chances are that if you are the right man for her she will want to have children. Often it's not that someone doesn't want kids...they don't want kids with HIM in her case.
Just keep enjoying yourself. Enjoy in the moment & repeat.
