Thank you so much for posting this Alex.
I'm young enough for marriage to seem distant, and my parents are still married, yet more than half of the children I grew up with had divorced parents and I have several separated family members.
It's not uncommon for most of the families on a suburb block to be divorced, especially in certain areas (most of my affluent white friends had antagonistically divorced parents, mainly due to money)[1]. The U.S. still has a large problem with divorce (~50%), and especially with divorce among families with children.
Divorce is far too often considered "taboo", as stated in this article, which is quite a travesty because I've found discussion can provide great benefit to not only those already affected by it, but those contemplating long term relationships. We consider divorce a "failure" in modern society, and in my opinion that's very often not the case. Many times divorce can mean simply a resolution of irreconcilable differences. However the law, lack of openness and general societal pressure can turn even amicable splits ugly.
In the end I've found closure like the OP describes always the most helpful: realization that life continues to go on, and even things that you relate with the old relationship (in this case, technology) will still be there as they always were.
[1] I feel it's important to note that divorce rates are highly variable dependent upon ethnic groups and demographics
