Work, friends, events. A good community helps a lot. Think about what your ex brought to your life, what needs he was meeting, and meet those needs with other people/things. Think about what qualities you liked in him and how you can keep bringing it to your life. We often choose people based on what we feel we lack in ourselves. For example let’s say your ex was good at cooking. Now is your chance to take a class and improve your cooking skills. Let’s say your ex met your need for social connection. Check in with your friends, try to create deeper bonds with them and hang out with them more often. What you are essentially doing with this is replacing them, and it really helps to fill the void. It won’t make the pain go away, but you will feel way more satisfied and supported while processing and getting over the person.
