Firstly you have completely confused the time line. The wife probably met the other man AFTER marriage. This can happen you know! Also losing respect in front of society is rubbish. Is your life important or what society thinks of you? Only fools give importance to outsiders who don't care about them anyway. If she remained in the marriage it could be adultery. Here this is not the case. Her husband thinking he is smart filed an abduction suit. The truth was different and the court has tuled correctly. Do you think just to keep your neighbours happy you should accept a miserable life with someone you cannot respect or love? Isn't divorce better? The husband too can probably find a better suited wife for himself. Why are you crying?
