You must trust the ones you love. You must trust everyone but specialy the ones you love. Give them everything in you, everything. Trust them the truth, harsh or not, trust them your hole heart and all your fears.
Trust them in spirit of the one who alows mistakes. In who understands if they cannot bear such responsability. If one day they break your heart you will know with all the broken pieces, you've loved like few people have loved, you've been happy like few people even know possible to be.
And in the future repeat it all over again. Remember not the sorrow, not the sadness, not the lack of sleep nor the pain. Remember how good it felt to give someone all your heart. To trust someone all your heart. Even if they let you down.
Nada acontece por acaso.
