Children when parents decide to seperate

My wife has decided to separate because of reason that has happened is beyond repair. She asked me to get out of the house and I did, I reassured kids I am going to be back as they are still under 10. But my wife has decided to be separate. I am in another city at my relative. She been talking to kids about what happened and how dad is not gonna live with them. I have met them but she is not happy for me to meet like that. I want to know what rights I have on my kids, how can we make sure kids upbringing is co parenting. What goes Islam says about it? This is the second time she told me to get out of the house even I tried to separate the bed once but she won’t leave me alone. She has anger management issues. I wanna know in light of Quran how and what to continue when kids are involved.
