A SAD DAY!

So today my son will go to live with his father. I am so very mixed about this. I know that even if i do not approve of many of the things my ex does...he truly loves our son. For the last 12 years with the exception of visits to dad's house...I have been the only constant in his life. I miss him so much and we have just begun our time apart. As a realist i know that there are things in a boy's life that only a father can teach....but at the same time, it is like cutting out half of my heart. All that i have done for 18 years now has been based on what is best for my children...and in the last 7 mts. two of my children have moved out. My eldest just grew up and flew the coop. A very sad thing but i did my job to the best of my ability when it comes to raising her. Oh but my not so little boy.....moving in with his dad......this really hurts! I hope that all of the energy in the universe will be there to protect and keep him.
