Even though strong women are likely able to handle assholes better than most women and men on Earth, they shouldn’t have to do this—and they’ll almost certainly be happier if they don’t bother.
Dating can easily be the best use of your time and energy, but it can just as easily be the worst use of your time, energy, and life. It goes without saying that no relationship will be perfect, but when the number of imperfections increase to a certain extent, there is virtually never a good excuse to continue moving forward (or at all) with your partner. Even if they depend on you significantly and their life will be negatively impacted without you, these facts do not outweigh the truth that happiness in your life is being stolen by your devotion to your partner.
Most men have at least one quality or two that makes them desirable, whether it be a fit body, good looks in general, above average intelligence, or humour, wit, etc. However, keep in mind that most human beings possess at least one desirable quality, so this is not a good enough reason on its own to enter into or stay in a relationship. What’s more, the negative characteristics that almost always accompany the positive ones—such as lying or cheating—more closely resemble choices rather than traits: these are behaviours which can be corrected, but which are persisting nevertheless.
One way to avoid being dragged into these relationships, or to avoid being dragged along with them, is to genuinely be happy while single, and to simply be open to additional happiness with someone else. It may seem as though being single is lonely, and it certainly can be. However, being in an unhealthy relationship can be extremely lonely as well (perhaps more so).
Quite frankly, actions must be considered and judged with more seriousness than words are, and if you are not being treated as good as you should be, you must act for the benefit of both people in the relationship. After all, these types of relationships never last (or at least they shouldn’t), and the sooner they end, the sooner both of you can begin to recover, move on, and move closer to real happiness.
Buddha may have said it best: “You yourself, as much as anybody in the entire universe, deserve your love and affection.”
