In love, we all have different types of sacrifices.
It's either you keep it hidden from the others to keep your relationship going, or go wherever he is no matter how far you go, or you might able to change what you use to for that someone who doesn't even know your worth.
You were just simply a friend and someone who were given a chance to listen to their words of wisdom.
You decided on your own that you never did before.
It's awful but that is the only way you know to be with him.
