Learning how to be alone is the best thing you can do for yourself. Don’t depend on someone else for happiness. That comes from within. Do what makes you happy because no one else will.
Relationships should be complementary. Anything more and you’ll lose yourself. Anything less and you’re better off without. Follow your heart, but listen to your head, it will keep you from getting lost. Sometimes it’s ok to get lost because finding your way back is how we learn and know better for next time. Even though every day is an uncertainty, we can find certainty in the choices we make.
Choose to be happy and the rest will follow suit.
