I have never understood the concept of soulmates, twin flames, being one half of a whole.
I have never needed somebody in my life to make me feel whole because I am absolutely complete on my own.
Self love is important. When I hear about those who can’t enjoy their own company, I pity them because I love myself (not be or sound egotistical) in the way that I genuinely enjoy my own company. If this doesn’t resonate with you, try taking yourself out to lunch, going hiking, seeing a movie by yourself. It’s scary at first, but freeing to be able to be friends with your conscious.
