My girlfriend left me?

She was working in my country and she returned back to his country to renew her passport. She mush have come back here before 14th to expand the work permit. I explained it every day several times to get her passport at 13th. She did not listened me and she couldn't be able to get her passport. It's really hard to get work permit but I have very strong relations with powerful people so probably I'll able to get a work permit. I called her and refused to come back, I appealed her , pleased her for our love, I gave a promise to marry with her but she is refusing. I don't know what to do. I really love her and I can give my life for her, why she's doing this she loves me too ?
