I always think that it's weird when leaving someone turns out to be the best option. If you're at all like me, relationships these days are all about a careful process of selection. Personality-wise, I am not the type of person who solicits anyone and everyone for friendship. I make friends and then I tend to want them to stick around for the rest of my foreseeable life. And why not? It's not that difficult to maintain a friendship- the care and time and effort required is much less than a commitment-heavy romantic relationship, or the life-long blood ties that involve family relationships.
For this reason, it's always hard for me to wrap my head around the concept of losing friends. I'm not talking about the typical, "She moved 3000 miles away and we gradually lost touch but if we ran into one another there would be hugs and laughter"- I'm talking about the conscious decision to terminate a relationship with someone you love. If you've had friends that have been around for a few years, the likelihood is that sooner or later stuff is going to come up and the decision will have to be made whether to try to stick it through, work it out, or leave.
So when do you leave someone? And, if you leave, is there ever a time when it's okay to come back again? Does leaving someone mean that you didn't love them enough? Does returning to someone whom you've left indicate that time heals all wounds, or does it establish a return to old habits, addictions, cycles that will cause history to repeat itself?
Obviously, these questions are a case-by-case sort of thing, as is any personal relationship. There is no diagnostic book that can tell you the signs and symptoms of emotional regression within a particular relationship. However, I guess the reason I post this post is this: sometimes we have to leave. Leaving is not the worst thing. It is just one of a few uncomfortable options when problems arise. It can be the wrong choice, and it can be the right choice. And, just because it's the right choice now, doesn't necessarily mean that returning is the wrong choice later. Unlike chemical elements, people change and relationship compositions change.
