You need a clean slate my friend.
I read a book after my ex wife left called "The 5 Love Languages" by Gary Chapman.
It was too late when I read the book but it definitely helped me understand why my ex left. We did not have the same primary and secondary love language.
I know it sounds dorky but it should helped me understand how and why a woman's emotions control their thought process.
I'm actually better off without her but sucks for my children.
The book has helped me meet amazing women and when they find out I've read this book, they are blown away. But work on what you have left and tell her you're going to read this book right now before it's too late.
All the best to you.
