One of the most difficult parts of moving on after a divorce is to figure out who you are without the other person. This feeling of uncertainty is natural because no matter the length of time of your marriage, a piece of your life and personality was conditioned to be a certain way with that person.
Divorce has its challenges and keeping your confidence intact during this process is certainly one of them. You are learning to be single again, and adapting to life without your partner can shatter your self-esteem. For this and other reasons, even if you are the person initiating a divorce and leaving the other person, your confidence could be affected.
