Hang in there! Having gone through one divorce I can say that in hindsight she was right for leaving. We did not have a good relationship and although she gave up without trying I can now say she saw what I didn't. Now going through my second I never thought I would be here. I found someone new that is everything I wanted in a wife and relationship. Problem is there are two people in a relationship. Communication I key and things need to be worked at together. You will get through this as I know I will but the emotional rollercoaster is real. I can actually watch myself moving through the steps of grief over and over. Don't beat yourself up and don't look to far into the future or the past.
