I honestly don’t know. Believe me, I wish I could have the power to make that happen for you. But consider this, without focusing on your own personal growth and investing in creating an amazing life for yourself, you will find yourself with the exact same problems if you were to just get back together.
The goal of therapy is to work on YOU. Rediscover hobbies, take better care of yourself, focus on your goals, overcome your personal hang ups, and make new friends (or strengthen current friendships). By making yourself a priority you can be in a much better place to have a fulfilling and satisfying relationship no matter if it is with your ex or someone new.
