Mayankji... have faith - whatever God does will be the best for you. If shes not meant for you, irrespective of what you do it wont work out. If she's meant for you... nothing, no one, no time and no event can stop her from being yours. Keep the faith strong. Sometimes we expect God to work like a ginie for us. We think if I pray this much this is what God needs to do. Unfortunately we all think that way buddy. And unfortunately it doesnt work that way.
Have faith and love others... serve others. Spread love around instead of expecting results. And trust me you will be blessed with much more when you do it without expectations. My prayers and best wishes with you.
Om Sai Ram
