Han in there fellas, 12 weeks is still very fresh. Soon you will start the turn towards calmer waters. Give a month or 2 and you will start rising.
Barry, you gave get your focus of your W and onto yourself, STOP with the pursuing, you can clearly see it does you no good. Your wife is lost to you now, you might as well be talking to a brick wall. You have to let her go and start working on yourself. Start building your confidence up, start making your life a great story of success. Be the best dad in the world for your kids, become the great man that you always wanted to become. Be the role model for your kids. Make them proud. Start living your life today!
There will still be crappy days and lonely nights, but the will become fewer and fewer.
