Is it normal for a married couple to separate once the kids are grown and out of the house?

Lately , I have been meeting a lot of divorced women, they say they are divorced and I meet women that are separated from their husbands , that said they went there own ways , when the kids were out of the house , Empty Nesters pretty much , Is it normal just to give up on your marriage, because the kids moved out? What’s the point of even getting married , if you plan on leaving each other, once the kids are grown? Isn’t the whole purpose of marriage to stay together until death do us part? How would you feel if you married partner, told you they now want to go their own way and live their own life once the kids are out of the house? Would you be ok baby , I understand , I wish the best for you, or would you be like you F’ing SELFISH BITCH!!! Thanks for pretending you loved me all these years
