One end is a new beginning.
There are times in our lives where we have to make hard decisions. These decisions come about in many different forms; they can be towards a person you love, or a place you've come to call home and the most important can be because you love yourself. It's called setting boundaries. It's called respecting yourself. It's called life. Don't regret the years and special moments you shared. Be happy and thankful for the experience. Use the negative experiences as a stepping stone to know how you never want to be treated again! And move on with your life.
