Hey Raghu, this is ditto my story but you got your girl and then your friend back. I lost both! I still have good relation with my buddy but not like before ... and me and she both got married long back, I am happy with my wife and kids ... don't know about her as I haven't seen here and spoke since 12 years. I prey for her happiness ... never thought this could ever happen ... the culprit was cast difference but it wasn't that significant.
Sometimes i wonder whats the fault in love with friend's sister if u think u r good enough a candidate to be considered. U dont need any background checks, u know him as a friend, and if he turns out to be a family man its even better... unless the love is purely platonic ;)
you should thank your wife for everything. She loved you so much that she even sacrifice her own brother to marry you... Just imagine if she was not able to do that... so love your wife and make her happy always. That would make your best friend more happier. Enjoy...:)
