You don’t actually need a reason to file for divorce. When in doubt “irreconcilable differences” is the catchall reason.
Grounds for divorce are only used when one is seeking something more than an even split of the marital property or something more than joint custody of children. Something to show that there is more to the dissolution of the marriage besides couples not getting along anymore. In every state “Cruelty” is listed as a cause which traditionally covered spousal abuse.
