Stillalone, I spent a over 20 years with my X, had 4 kids, and he walked away and married the OW 14 days after we divorced. Do I consider it time wasted? No, because I came out of it with 4 beautiful children. How can I regret it when I have them because of the relationship. I spent some time mourning the loss of my family, then I realized that I am still a family with my kids. You also have a family, your daughter. Celebrate what you have as you move out of mourning what you feel you lost. Over time I came to realize that the relationship I was mourning never really existed. I was mourning an idealized version of my marriage. It sounds like you may be stuck in that phase also. Take time to evaluate what you had then and what you have now, and learn to rejoice in the now. Live in the present, you will find happiness.
