Couples who divorce, but continue to be parents, do meet up to discuss the future of their children. Does a divorce mean they are separated permanently? One relationship ends, but several others continue. Many of these couples continue to be friends. There is less bitterness, more acceptance and forgiveness.
Many couples also live separate lives. They are not legally divorced, but no longer share the same roof. Due to various reasons, living together is not an option. They are not separated due to working in different geographical locations, but due to not being able to live as husband and wife. But they too meet for the sake of their children. Going through a divorce could be financially expensive, so they prefer to be separated. Of course it means they cannot marry someone else, but for many that is not an option anyway.
There are a few things that are permanent in life. Most things are in fluid state. Even relationships. You make friends, you break up. You could resume the friendship later. You lose touch with some friends, but could meet up after a few years. All things are possible.
If you feel a broken relationship cannot be healed, it is not right. If you are willing to forgive and let go, the healing will happen. The relationship may not resume to the earlier state, there will be changes. People grow and hopefully mature! So a broken relationship can be resumed, without hoping that it will be on the same plane as before. It can be, it need not be. This must be understood and accepted.
Nature too gives us this lesson. The Sun rises in the East and sets in the West. The Moon waxes and wanes. The tide comes in and recedes. But the Sun does rise again, the Moon does wax and the tide does return. Nothing is permanent. They do return and resume. So why not relationships?
You would be estranged from your parents, siblings, friends, neighbors, etc. You would have had good reasons to be. But time has elapsed, much water has flown under the bridge. If you let it be, the relationship will never resume. You can take the first step in making amends. It need not be to rehash what happened. But to resume with the positives that were there and to try and build upon.
When a breech occurs in a relationship that was meaningful, there will be hurt and pain all around. A separation will help and this can lead to some introspection. With maturity will come the thought that this relationship can be resumed, if both parties are willing. Siblings have got back together after being separated for years and so have friends. Who is right, who is wrong does not matter if the relationship is meaningful and the parties involved want to resume.
Maybe the old hurts will be addressed. But in their own good time. As you grow older, you mature and so does your relationships. If you insist on being immature, then your adult ego state is being contaminated by your child ego state. There will be irritation, attempts at attention seeking behavior, and friction.
So if you start to think about a relationship that has drifted away, try to recall the positives that were there. If those positives are still there, then do extend the olive branch. Remember a relationship can flourish when both benefit from it. It should lead to growth of both parties involved.
See if there is any relationship which you have allowed to drift. If you wish to resume it, you can. You need to offer unconditional friendship and a resolve not to dredge up old hurts and pain. There is no point in revisiting the reasons for the breakup. The breakup happened, you are to focus on the resumption. Explanations can be offered when the time is right, or not delved into. The need to heal should be genuine, even though the rules would have changed. Since change is the permanent thing, one needs to embrace it and move ahead.
You can make new friends and relationships. But the comfort of old relationships is something else. Like a well used blanket, maybe torn a little, but comfortable nevertheless. Pick it up and regain the warmth.
