Looking forward

I am becoming drained from going through this divorce.  While it is still new, I am putting so much effort into it.  All of the work to make sure I get what I need from him through the courts is exhausting.  Meanwhile, he is out living a carefree life.  I know that I will never get a straight answer as to why he chose another woman (women) over me, but that question still is in the back of my mind.  How can you just leave your family, your home and your life for clubbing, sleeping with other women and Facebook? 
I told myself this morning that I am going to focus on my sons' and I today.  I am going to do my best to put my attention to my STBX's behavior on the back burner.  Mornings are the worse because my mind is rested.  I need to gain control of my mornings so they are productive for me and my boys and not damaging because of the thoughts of him.
I cannot wait till the day when I wake up and do not give a f%#$ about what or who he is with.  That will be a glorius day.
