I won't say they have become more realistic about marriage, it's really more of them not being willing to tolerate what comes with marraige. If only they understand what Marriage means and how it would benefit them, they will be willing and tolerating will be very bearable.
I get your point, but I think there's a difference between understanding what marriage requires and simply tolerating everything that comes with it. Some things require patience, while others shouldn't be tolerated at all. Where do you draw that line?
I guess having the knowledge of what Marriage requires is a first step to knowing if you can go through with it or not. Because if we look well, life teaches us what we may see in marriage through family, friends and strangers around us.
But that teaching doesn't mean the new marriage should be like that. In fact, it's better not to look at the marriage of others cos we humans tends to project what we see consciously or not
I didn't say look at marriage of others though, I'm saying you can learn from how you react to what people do to you, especially your loved ones. It's mostly what will happen in marriage, actions and reactions.
Having non negotiable on your own will be the line you can draw, I believe a lot of us know some of things we can not deal with by our capacity, watch out for them before marriage.
