Got engaged 6 months ago. Fiance promised to marry me in December. Last May, he went home to his family for a quick Spring vacation. We communicated for less than a week and after that, I didn't hear any more from him. I reached to him on Facebook, sent messages but none of them were read. Tried calling him on Skype and on the phone but he never answers any of my calls. I also reached out to few of our close friends but no one has any idea of what's going on with him. Shall I give up or wait patiently?
