You will never be as alone as being with someone who makes you feel alone. Another person can’t complete you. They’re simply a partner on YOUR journey. If it doesn’t work, it wasn’t right and you can’t fix it into being right. Don’t dwell on things, it hinders growth. You don’t need them, you just want what you can’t have. Love yourself first; the rest will fall into place. The second you realize this is the second you’ll discover true happiness.
