Mental and physical abuse by wife

Dear legal team, My wife has been abusing me and my family(mother, father, sister, brother, cousins) verbally. Sometimes, physically abusing me right of my son(10) and daughter(4). I had to defense myself and not to abuse her back physically. Background: We migrated to a foreign country a couple of years back and I lost my job due to war/economic slowdown. I am not able to secure a job untill now. Since then, only my wife is working, she keeps abusing me for not finding work and for every small thing. She keeps harassing me mentally everyday infront of kids. I was ready to take kids back to India and take care of them completely as we have enough money back in India. She threatens saying she will file a harassment/dowry case against me and my family back in India. Will the police come and arrest all of us directly after my wife files a complaint? Can woman take an adavantage against her husband/family so easily? I am really depressed in my married life. Kindly throw some light and support the suffering husbands.
