Is there any way or any chance to bring up positively this relationship?

If you truly want her back, and you agree in the hearts of hearts that a girl will need your time specially when you already made physical relation with her, there is only one way out. Take some money from any of your friend or relative and go meet that girl's family. make sure you carry your medical reports along with you. Just make one true effort and let them know what all you have been through, and tell them that you don't want to live with a guilt of spoling a girl's life, so you came all the way just to tell the real situation which they won't hear over the phone. Tell her parents that you still love their daughter truly and it was not intentional at all that you did not talk with her for 3-4 months. i hope they will understand. you will get your love back. now only one problem is left, and that's about wedding. tell them, you can have a simple marriage right now and only call close relatives and that's it. introduce the girl to your family and i'm sure the lost trust will be regained. now only one problem is left, and that's about getting a job. make it clear in the very beginning that you have lost your job because of recession and also because your manager manipulated data. The only point it, do you really want to go to india and do it. it will cost you a few thousand dollars.
