If I can add my experience... if, even to yourself, you refer to her as the love of your life, that will make it much harder to heal for you. I know that it will not be easy to stop referring to her that way, but you have to. Also, social media makes it harder to heal, because we have access to people's photos. That is not the way nature intended it to be. You are doing a disservice to yourself by constantly reopening your wound when you look at her pictures. You need to distance yourself from access to her, for a while. Give yourself 3 or 6 months, to start with. Block her for that time, and allow yourself to heal so that your heart can welcome love that is healthy and beneficial to you.
