what is the longest marriage that u know to end in divorce

Are they better off now? What were there differences if you don’t mind me asking? Anybody remarried? Lately it seems like we have hearing about so many people filing for divorce. It is always sad to hear when a new marriage doesn’t work out. But even worse when marriages that have grown kids to part ways. I have been feeling really depressed about this new emerging trend. family is the foundation for society …that’s what I was always taught. Very few marriages I know of are perfect. Most of the ones I know ppl have had there fair share of discord and spats. Hollywood marriages are different. Any marriage in the public eye is sort of doomed. But I am trying to understand what goes thru people’s mind when they decide to call it quits after 20, 25, 30 years? does something snap in their mind?
