Yeah, divorce was common back then.. the sahaba used to divorce and remarry quite easily back in the times of the Prophet (PBUH).. they had quite pragmatic views on marriage and relationships..
Our culture has attached a lot of stigma to it when in reality if a person has an actual reason to divorce in Islam (eg they no longer love their partner or a marital right isn’t being fulfilled, let alone cheating or abuse) that is considered enough to terminate a marriage..
Being a ‘martyr’ and staying in a loveless marriage for the sake of God isn’t from Islam..
