Hi Luis, don't be sad my friend, it happens to all of us (Loyal and generous people). Be hopeful and try again and again, I am sure you will find your dream partner. You are a good person and let this never change you. Smile and look-over and consider that you bought experience with this money. I myself faced a lot of this and I didn't stop trusting and giving and my reason to myself was: Maybe they need this money more than me! Forgive and forget. All the best luck!
