I have seen this happen quite often, two couples divorce and within months or less than a year they both have remarried.
Somalis don't care if they been divorced 10x they will move on to the next husband/wife.
In other cultures like Indians and arabs this is looked down at.
The trick for couples to be together for a long, long, long time, u have to do a math.
Find someone vastly better than you, or someone vastly worst than you.
The power dynamic has to be stark.
One spouse has to be desperate.
For example : if you are good looking find a spouse who is ugly
If you are rich, find a poor spouse and make sure they depend on you. (farah from the west marry a fob wifey and leave her in somalia. and Xalima in the west the same)
Or make things less complicated
Be Pious & someone of high Diin and marry a spouse who is higher in diin or same. With diin, the balance will be naturally balance as both of you will fear Allaah swt
