Everytime im in a relationship, I cant help but to think i can find better & that theres someone else out there for me. Why am i this way?

When you get that feeling, your gut is telling you that you can actually find someone better than the person you're with right now. I know how it can feel like something might be wrong with you, but it just means that the person you're with isn't the right person for you; but, once you find the right person for you, the person that you are meant to spend your life with, you will never again feel like you deserve to be with someone better; that person will be someone you look forward to seeing and being with.
