I know about 3 friends personally who have had issues with abuse. One was full frank abuse. The other two were more like mental abuse. One of those had questionable physical abuse but it was sad that no one believed her even though supposedly she showed people bruises. I never saw them as this happened in Pakistan, but even then, relatives said she probably self-inflicted the bruises and she could not possibly have been seriously hit.
2 were smart enough to leave. The last one still remains with her husband as her family did not support a divorce at all. I don’t know what their deal is now, if they’ve fixed their problems and if he’s still hitting or not.
