My terms with my in-laws weren't good either, My in-laws were always rude and they used to assault me too in various situations. They used to tell me that my husband is going to take my kids and will kick me out from his home and he gonna fly to usa with kids , and going to dump me in India and police is not going to get there because it’s a different country . And on 29th of June Wednesday (india time) he took my kids when I was not there , my brother in law and my sister in law forcefully took me to shopping and when I came back i realised my kids are not there and their passports, along with my passport and all other kids stuff were missing.
