NO ONE IN THE ENTIRE WORLD is going to love you the way you can. Don’t look for validation in man because we will ALWAYS let each other down. People have their own lives, their agendas, their own desires, etc. and while they may genuinely love you, their ideas, methods or examples of showing that love may be totally different from you.
Rejection is hard. I'm pretty sure everyone in the world either has or will at some point have to face it. It's not fun, it can often leave us feeling unwanted, undesirable and make us question whether or not we're "good enough"
