its difficult for me since i'm befriend with him for like 3 years. he said he doesn't have a girlfriend and all of sudden he asked for my advice for his 'love'problem with her gf. i'm so hopeless. anyway, thanks for your words. i really appreciate them..;(

All you need to do right now is love yourself. Just because that guy doesn't appreciate what you appreciate about yourself doesn't mean other people don't. There are other guys in thie world that are just as worthy as he is. You will heal if you let yourself. The feeling will fade away, so just try to distract yourself. Exercise helps relieve stress, and maybe take time to do a favorite hobby. Good luck in the future <3
