If that's the case, then we also have to admit that there's generation of young women who dealt with the same thing. They would also be traumatized. In addition, I feel like it's worth mentioning that most women don't become single mothers by choice. Usually either divorce happens, or the father just skips town. If we're going down this route, we would also have to acknowledge that there's a generation of young people whose fathers either didn't play a huge role in their lives, or were just entirely absent. This, along with what you two have stated, would cause trust issues on both sides.
Look, when it comes to a topic like this, you really can't boil it down to one issue as being the sole catalyst. We can point the finger at society, economics, feminism, technological and/or medical advancements as being the only reason, but when it comes down to it it's a combination of these factors.
If I had to sum it up, it's that, well, times have changed. The world has socially and technologically progressed more in the two centuries then it has in the last two thousand years. It's honestly kind of scary. What we have accept is that these changes, barring a huge catastrophic event, are here to stay. The old ways aren't coming back, and nor should they.
Modern life, for all its, many, many faults, is still a hell of a lot better than yesteryear's.
