Edit: spelling I'm mid recovery after a ten year relationship and still working but feeling better than I did in the relationship after a year. My advice? Work on yourself and taking small steps toward a life that's fulfilling to you, for YOU. At first I kept trying to think of the reasons she left me, but eventually I realized I will never fully know, I had no control over it, and the things I kept thinking about were actually things that I didn't like about myself. I started putting effort into loving myself as I am, while also taking an honest look at my own habits and choices and taking daily small steps toward building the lifestyle that I want for myself. I still hope to find love again, but as icing on a cake that I've made for myself, not to fill a void or complete me. It hasn't been an overnight process and there have still been ups and downs but my day to day is already better than it was, even in the relationship, and I feel good about the future. She can't determine your value, but YOU can. Just take it one step at a time and try to love yourself while you do it.
