It was the only one I ever knew as well, so I do know what you mean.
How do you think the Catholics pre-Vatican II felt when all of a sudden the only mass they ever knew was taken out from under their feet? And until Benedict XVI came around it was gone, period. There was no choice to attend one or the other.
Perhaps you should start to think about the fact that the Catholic Church did not start in 1960. As a former Novus Ordo Catholic, I’m telling you that things changed big-time. We must learn our Traditional Faith. It is not the same as the Novus Ordo Faith.
Maybe, just maybe the ordinary mass simply was going back to the “roots” of the Church, that is, the early Church:

Every town in the world has a Catholic Church that performs the traditional mass. It is not forbidden.
