In the modern era of no-fault divorce, if one party wants to dissolve that which was joined together, "for better or for worse, and till death do us part"; signifies that sentiments and vows such as that, basically play no relevancy whatsoever, to whomever wants to vacate said marriage; along with those in a serious relationship, for that matter. No doubt, because it is so easy to break those bonds and in consideration that for the most part, society does not treat those that have been divorced or have left committed relationships, in a manner in which they have been banished from that society, there thus remains nothing much that classifies such as being some sort of disgrace or even necessarily of being in error.
Unquestionably, some people should definitely get a divorce, and no doubt, some people should separate themselves fully from a toxic relationship, but in view of the fact, that a significant amount of people that sever important relationships, end up getting back into another one; it might behoove people, in general, to understand better what may be the thing or things which went wrong or were set to go wrong, in the first place.
To a significant degree, a lot of what goes wrong in relationships of all different types, fundamentally comes down to selfishness. In other words, far too many relationships are essentially a series of couples often talking pass one another, and simply expressing their own desires for their own benefit, and to the degree that the other person can help fulfill those desires, then that person is "loved" or appreciated, and to the degree that they do not, then they are "hated" or despised.
So then, whenever a relationship is fundamentally structured upon what the other person can do for a given person, then obviously there is going to come a point in which either that person so desiring that submission to their desires, will become disappointed, or that point when the person submitting to such, will get sick and tired of doing that, or both. A healthy relationship, on the other hand, is always going to be that one, in which both parties to it, acknowledge that each of those parties, has intrinsic worth, and further that in order for two heads joined together to be better than just one, that those two joined together, must be in harmony with one another.
The grave mistake made in far too many relationships, is the wrong perspective taken by one of those members, or both, of believing that what a given person so desires, trumps all; as if the other person rather than having unalienable rights and therefore their own free will, is meant instead to be subservient to someone else, for that persons' particular convenience and pleasure. So that, what often transpires, and thereby fools those that are part of those relationships, is that one party decides that they will be nice and considerate, not really because these are good attributes to have, but rather as a way to manipulate the other person to do what they want to be done; and when that other person no longer buys into that false construct based upon a facade, then thereby all is exposed for what it really is, which thereby leads to those relationships' subsequently falling apart.
