SaiRam dear Dipesh Bhai. If you really feel awful abt past deeds, could you not contact your wife directly or through your/her relatives and reason with her and ask for forgiveness? Forget abt astrologers or anyone else, what does your conscience tell you, do that and leave the rest to Sai. With most sincere and true heart if you can apologize and confess to her and follow Sai's guidelines, you may find happiness.
Aum Sai Ram !
