Once you realize you cannot move forward in the marriage any longer with your spouse, it is time to proceed with a divorce. As you acquire the necessary paperwork, you will gradually inform your loved ones of what will happen. Chances are good you know plenty of people who have divorced, and they will likely give you advice during this time.
You need to take any advice given to you by friends with a huge grain of salt. Divorce is different for everyone. They may be familiar with the process, but they do not know you and your spouse. You should only take advice from a legal authority and only rely on your friends for emotional support.
