Do not be confused by the first quote because it is from a non-Muslim, and you are seeking advice from Muslims on Islam.
I am the Muslim who posted the second quote in your last post. Now to your question on the second quote.
My question is what are the Islamic matters you know better than her?
Do you know enough to be able to lead her in Salah, when the two of you are at home praying together?
A young Parisian man walked into a boutique and saw a girl with hijab. He talked to her and returned there often. He fell in love with her and asked her to marry him. She of course said he had to convert to Islam of his nconviction before asking for her hand. He did, and then she referred him to her father, who agreed. On the first night, the girl asked her husband to pray isha first. He wasn't quite well versed in that, and the girl led him in Salah. After a few days or weeks or months, when they stood again for Salah, the girl pushe him to the Imam's position and told him it was his right and duty to lead, and that she had done so only because he was not learned enough. Now he could and should lead the Salah in their home.
The girl was an Afghan who had ended up in Paris due to the Afghan diapora brought on by the Soviet invasion in the 1980s.
It is necessary to try and become a better Muslim. Learning and practicing what you learn is a life-long process, but there is no rush to learn eevryhting in six months or so. You have to learn the most important bits first, and then to more detailed matters.
I would suggest some sort of structured learning is always better, but you do not have to attend Islamic learning classes before reverting to Islam. Ask the Imam at the nearest masjid
