My story is similar to yours in that my ex wasn’t invested in the marriage the same way I was. I felt unloved and unsupported. I left a lot of stuff behind when I moved out. The interesting thing is although I make 1/3 of what I had in my marriage and live in 1/3 of the space I feel far richer than I did when I was married. I’m far happier. I can relax and finally be myself. My mental and emotional health is far more precious than anything else. Best wishes to you.
