I don't know about you - but I find myself thinking that I should feel grief when really, I feel happy and excited for the new future in front of me.
People do the head tilt and say "Oh I am sorry" when I say "I am no longer married" and my first thought is "don't be, I'm not".
I am living in a house I love, fixing it up the way I want it, my girls are calm and settled and dare I say, happy?!
But like you, some days I do get angry. Those days I have to physically tell myself (usually in the car in private!) to STOP DWELLING and evict the person living in my head rent-free.
Those days are few and far between now. For that, I am very, very grateful. I hope you are, as well, because you sound great!
Live each day as it comes, and not on what some prescribed theory says it should be.
Keep on keepin on!
