1 month to the day after 15 years

Just started writing a blog and wonder how this thing works. Today marks the 1 month to the day of the end my 15 year relationship. How do I move on completely? How do I explain to my son that I am not going back? How do I keep my strength up not to go back? Is this 180 mile move worth my sanity? All questions that have gone through my head all day all night everyday. I still haven't found the answers! Maybe this blog thing will be my sort of release therapy? IDK? But what I do know is, I have my son, my sanity,my job, and I will be ok in the end!
