Truth,
Just because there is a good valid reason for divorce, doesn’t make either spouse automatically blameless. Sometimes, two lovely people bring out the worst in each other and can’t make their marriage work, even after trying.
Every person brings baggage to a marriage (first or 31st). If the baggage you brought to marriage contributed to problems in the marriage, and you don’t fix the problem, then even if you marry someone else, the problem is still there. It may not be a problem with the next person, or it might.
Also, if a woman is abused by her first husband, she may be blameless in divorce, but if she doesn’t take care of herself (usually involving therapy), she may have problems in her next marriage. Either becoming a “victim” or becoming so sensitive to abuse that she will attack her husband at the slightest thing and call abuse. Granted, I’m slightly exaggerating, but you still need to take care of your baggage to make the possibility of a healthy marriage truly work.
