Lost and confused

I am divorced but still have a business with her. It was both our 2nd marriages. We met got engaged a year later married a year after that. When we moved in together it started good, but, the kids tore us apart. She guilty parents and let hers do whatever while mine were constantly under a microscope. Their rooms had to be clean when hers she gave free passes. The double standards were out of control. Enough was enough when cops started coming to my house because of the bad kids her kid was surrounded herself with. I had to leave because it was getting to the point my kids didn't want to stay with me and instead stay with their mom. That was it I had to move out.
Why I am so lost is because I have never loved another women as much as her. I know it is over but I can not get her out of my head. My thoughts are about her all day. Somedays I just sit and stare at nothing for hours. The business doesn't help but we hardly have to communicate in person and do most through email and text. She is very hurtful and throughout the 3 year marriage has said some of the most awful hurtful things. I am very lost and confused.
