Things are way too fresh for you to see clearly. Over the coming weeks things will make more sense. Your conclusions will change and that's where the learning begins. And yes, you will trust again, once time has done it's healing.
Focus on yourself FIRST. Become a better version of you--a healed version--that loves himself and enjoys life once more. How? Do the things you like to do for yourself --whether it's a sport, some hobby, or spending quality time with family and friends. Everyday you will become more sure of yourself--you'll regain your confidence little by little. As for girls, stay away from them --romantically-- for awhile, you don't need to jump straight into another relationship or hookup with any chick. It won't do you any good. When you have picked yourself up and dusted yourself off--they will come to you. You will love and be loved again--and this time you will be wiser and more prepared.
