How could I get relief from the mentel torture of my wife

My wife always fighting with me in every small issues and she always threatening me that she will go wherever she wants without knowing anyone and also she will attempt suicide. It's being 4 years of marriage and we have one daughter. My wife only need sex in any circumstances and whatever my health codification but if she fells ill then it's ok. She also doesn't care about our baby also. She only think about her only. She knows that the law is with women so she is doing this kind of things. She also trying to ruin my career as she always threatening and tell me the same. Not only this but also she started fighting when I am in office. Today 1 st March 2024 also she did the same thing and threatening me that she will go wherever she can from her school ( Mega international school, Chandrapura) and can attempt suicide also on 2nd March 2024. I am really exhausted now. I can't take anymore. Please suggest me what should I do now. I really need help as I really want to come out from this stuipid things. I can't take it anymore.
