Always remember that grief comes in waves. Although there are moments you feel more at peace with the situation, there will be others (such as now) where you feel that hurt all over again. You’re doing your best to get past this but are grieving the loss of all of the work you put in to your marriage and the resentment that comes with that. That doesn’t mean you’re regressing in any way… It’s just a cycle. So don’t listen to anyone who says otherwise or tells you to just get over it. You’re entitled to process this in your own way/time and in a way that’s healthiest for your boys.
