My Testimony of Repentance from a Remarriage

I knew that there are grounds for divorce such as infidelity or abuse (both physical and verbal abuse) in a marriage. This is the first time I hear of someone repenting for a remarriage. Some Christians who divorce from their spouse and remarry don't realize or want to admit that it's a sin when there is no grounds for divorce but the Bible says it is a sin. Divorced people are free to remarry for the grounds mentioned above (infidelity and verbal and physical abuse) which excludes them from their ex-spouse if they're alive. The only people who can remarry without it being a sin is if they are a widow or widower.
