Pardon the poor pun. By "X" I mean "ex," and by "ex" I mean: "person-with-whom-one-had-a-previous-relationship-that-is-now-over."
Is there such a thing as staying friends with an ex, particularly once both parties have moved onto happy, permanent relationships with other people?
In most cases, I personally do not think so. I think that it is unhealthy to remain connected with someone from the past long after the relationship is done. I think that a desire to stay connected is borne out of a (sub)conscious lingering hope of reconciliation (and resumption of the relationship) with the other person. I think that if the ex wants to reconnect or remain in a friendship with someone long after the other person has moved on, that this is because somewhere deep inside the ex they are still harbouring unresolved feelings for the other person.
Of course, there are exceptions. I know of one, where the guy has remained close friends with all of his ex'es over the past decade. He is the only healthy anomaly that I am aware of. Other than that, I daresay that most people who claim to still be on friendly terms with their ex'es do not have healthy platonic relationships with them; there is always an imbalance of affection from one side, whether they claim that it is there or not. There is always one party who is holding on to what could have been, what used to be, and what could still be.
I am lucky that Hubbs and I are pretty much on the same page on this issue. He doesn't think it is all that healthy to remain friends with exes, either, so he puts up appropriate boundaries to protect our marriage and our relationship as his first priority. I do the same. However, I'm curious to know what others' experiences are like concerning this topic. I'm sure some of you will agree with me, and others will balk at my thoughts (which are just my opinions). Some of you will have lived the experience of being the ex, or being the party who has moved on, or being the significant other of one of the two. What are your experiences? What are your thoughts on the matter? Enlighten me. Let's discuss :)
