It's always amazing how little every day stresses and strains can make such a huge impact on our emotional state and relationships.
BTW, one thing my husband and I do which has been really good for destressing at the end of the day and it helps with communication is we try to take evening walks through the neighborhood. Just having a biweekly to nightly walk and talk after dinner and after the kid stuff is done is REALLY nice! It's a wonderful way to connect. I think it also helped save my marriage!!!
There is no arriving, ever. It is all a continual becoming.
