Yes! I left because my husband was having an affair (with a 23-year old, when we were breaking forty!....yuck). Happened almost four years ago. I had about a year of total misery getting over it, followed by a year of 'not feeling ready to move on' (I had been with him for 21 years, since age 17- so only man I had ever been with!).
It was a huge adjustment, getting over it, rediscovering myself, growing, getting my head around dating.....
But now, I am past my first anniversary with a truly wonderful man. He and I are very compatible - the relationship is far more passionate and fulfilling than my previous one ever was. He treats me infinitely better. My self esteem is way better. My sex life is off the charts in comparison,... and my new man is also much sexier- a true hunk....
My daughter has adjusted very well, after huge efforts on my part to make it a smooth transition and make sure she keeps her father in her life.
One final triumph is that in the four years since, my salary has increased so much, it covers the drop of my ex's salary being removed.
Getting to here was the hardest thing I ever did.... and also the best. I have no idea whether your marriage is worth trying to work on further - it may well be- but if your question is whether there can be life after divorce, It is definitely possible, OP! If you are tough and open to new experiences, the possibilities are endless!
