People are not truly in your life unless they respect you.
There can be people that you communicate with, get close with. People that you even touch and hug. People that you spend long nights talking with. Then one day you can see a picture of that person and feel so cold - you went from spending intimate nights together, not even sexual maybe, just close, and then that person is gone with no contact.
It's from these experiences that hurt our brain to grow and mature. These can be good experiences. But it helps to realize that someone was never truly in your life unless they respected you. And if they respect you, there's a good chance they won't be leaving your life.
But remember, respect is when you feel happy. Respect is when you can breathe and smile, and live how you need and live. Respect is people still being there after you do something to respect yourself.
