Living your life, the way you always wanted to, is possible even when you are in a relationship. Learning to recognize your emotions, continuing to work toward your goals and passion, learning to love yourself, and practicing certain activities alone are some of the many ways that can stop you from losing yourself in a relationship. Apart from that, investing your time in some new activities or hobbies can help you grow as an individual, and might help you reconnect with yourself and your new-found unique identity.
