I m Amarjit dob 22.05.79 & my hubby Harsh 10.08.84. Whats the future of our marriage & relationship?

Its a love marriage. I love him deeply and trusted him blindly. All my nears and dears were against my decision of marrying him coz they said his intensions do not look right. I am a Canadian citizen and he came to Canada on study permit and just want to get p.r. but I stood by him and thought that he is true but he proved me wrong and left me when he got p. r. But I have a child from himand I truly loved him. I m dying without him. We are separated for more than one and half year but I can not move on actually I do not want to move on. I dont wanna fall in love with anyone ever again. But he do not care about me and my son. Is there any chance or way that we can be together or he can understand my love and feelings for him??? We still see each other and there is something some sort of energy between us which always bring us closer when we are in front of each other but when he is away he do not even call or show any interest in us.
