With all of us going through so much change in a lifetime, some of our friendships can't last forever, nor should they.

Sometimes friendships gently fade away from starvation, as each person invests their resources in more satisfying pursuits. Other times, things like hurtful behavior, negative feelings, and attachment to memories of better times can make these break-ups a little more complicated and confusing.

When a friend mistreats you, or your relationship is on the rocks, it's distressing. The connection that has, at least in part, satisfied your fundamental human need to be seen, heard, and cared for, is now in jeopardy.

Especially since you've probably let your guard down with the person, the pain, frustration, and disappointment of the situation can readily transform into defensive, empowering emotions like self-righteous anger.

5 Things We Need To Teach Our Girls About Female Friendships

See if you can recognize and let go of those secondary, reactionary emotions, though. For one thing, they generally don't serve a useful purpose in the dialogue between the two of you. Animosity tends to breed more animosity, and holding onto that isn't a pleasant or healthy activity for either party.

Plus, the real problem isn't in those feelings. It's in the underlying mismatch and, for the purposes of the relationship, all that ultimately matters is whether that mismatch is capable of being remedied or not. Making that determination is easier with a more rational, less emotionally charged perspective.

Here's an example: say your best friend started making fun of you in front of other people a while ago. You've communicated to her a few times that you don't like being made fun of. She said she understood and apologized, but she's kept doing it.

Now you're torn because you know that being friends requires some degree of vulnerability and intimacy with someone, and yet you aren't comfortable being those things with her anymore. At this point, angry thoughts and feelings might well pop up: "Why can't you just stop? Why are you doing this to me?!"

While the answers to those questions might be interesting, they don't really matter, do they? You've expressed to your friend that her behavior is unacceptable to you. She's either willing and able to stop, or she will continue. If she continues, you have a decision to make: accept the ongoing mistreatment or end the relationship, at least as it currently exists. That's it.

Being the healthy person you are, you'd also need to consider if you have a part in whatever the problem is. If there is, then the same principle applies to you: are you willing and able to change things that are contributing to the problem, or not?

The point is that all you'll ever control, and all that you're responsible for, are your own words and actions, and the same holds true for the other person. Pretty simple, right? What is there to get worked up about?

Of course, it isn't always easy to maintain this rational perspective. Consider a best-case scenario: both of you have tried what you're willing to try, and it just isn't working because of an irreconcilable impasse. Even now, it may still easy for you to get stuck because of the positive feelings you still hold for your friend, and her good intentions: you believe that she isn't intentionally trying to hurt you.

This situation is similar, in some ways, to the distinction between murder and manslaughter. Whether someone's death was caused intentionally, it makes for an important moral, intellectual, and legal distinction to the prosecutor and defendant. But does it make any difference to the deceased?

If you knew that if you left the house today you would either be killed by a falling piano or an car accident, would you need to be certain which one it would be before deciding to stay home?

Sorry for using morbid example! But look: if someone is consistently hurting you, does it make a difference whether it's because they're unwilling to change or just unable to do so?

Lest you think that this perspective is dispassionate or non-emotional, let me be clear: I'm not recommending divorcing yourself from or denying your emotions. Far from it!

In fact, it's by paying attention to them that you are able to determine what need of yours isn't being met in the first place, so you can communicate effectively and determine how to take care of yourself.

What I am recommending is letting go, as much as possible, of the blame and anger that clouds your clear-eyed judgment and keeps you stuck. When toxic situations carry on for too long, with each person expecting or demanding that the other change, even though neither is willing and/or able to, that's when the hard feelings really bloom.

They may last a lifetime: the gift that keeps on taking! It's much better simply to keep perspective, keep lines of communication open, be clear on needs and expectations with others, be clear on what you are willing to give and take, and when an irreconcilable mismatch develops with someone that causes your quality of life to suffer, move on to people who are a better fit for you.
