What you wrote about your wife wanting the single life, free....whatever. My EXW said similiar.....guess what...There was a guy there. Very rarely do people leave without a safety net..
Now the good part.
I have an amazing life. I have great relationships with all our kids. I saved me and it was worth the trip. I choose to be a single father at this point but my GAL is constant. I have to turn things down many times. What I learned from this trip helps me in all interactions in my life.
You can have an amazing life as well. Save yourself because you are worth it. The journey of shaping yourself is worth it. Change the things you want with yourself so that if your wife does come around you have the chance for it to be better. If not you will be better for someone else.
