13. You'll Think That You've Made A Terrible Mistake
You'll feel so empty and alone (especially when the ice cream has ran out) that you'll think about your ex and believe that you've made the biggest mistake of your life. Even if you know for a fact that you weren't happy for the last six months, you'll remember the good days that you had. This is when you need to call your best friend so that they can tell you how miserable you were and how it really was the best thing that you've ever done. If you're not happy, how is your partner going to be happy living with a complete misery to be around? As selfish as it may sound, you need to put your own happiness first; it's your life and you don't want to have any regrets, especially about the person who you're going to share your forever with.
