You dont want to lose youth? Pay your lovely wife money, if you have taken dowry, return it, if her gold articles are with you, return it. In short, pay her lumpsum one time alimony and ask her to take back all these false cases, sign up MCD papers and let you go free. Thats one way out of this.
Second method is not legal. You go in for live-in relation, take the other person into confidence, confidence means such that, she should be able to tell if summoned to court that she is just your sister and that you visit her once in a blue moon. You will also have to manage the people in the neighborhood, so that they wont come and give witness in court against you that you are in a live-in relationship with that woman. You should also have goon power to threaten such people who would want to give witness in court against you, so that they wont come to court and give witness against you. If any kid is born out of such relationship, you should maintain the woman in such way that she wont come to court filing a PWDVA case against you and asks for rent or alimony or maintenance, you should part some money to her for her welfare at all times. You should not tie any kind of thread to the neck of the woman whom you have live-in relationship with. There should not be any photographs of you posing as husband and wife. You should have photographs of she tying rakhi to you, and you blessing her, in that particular photograph she should look like a sister with simple clothes, and not like a bimbo. In such event where she will come to court to give witness that she is not in live-in relationship with you, she should come with simple clothes and not like a bimbette and should leave the kid born out of such relationship at home or outside of court. Keep off of social networking sites. Use two cellphones, one whose simcard is registered in the name of the real brother or sister of that woman with whom you want to have live-in relationship, the other one which is the real one which you use for general activities for keeping in touch with mom dad etc of the legal family.
Now doing all this is illegal and would amount to bigamy, which is a punishable crime and you can be jailed for a good 7 years for this. But its all an art of managing. You could not manage one wife, so I dont think you will be able to manage the second one or the live-in relationshipwali that you want to proceed with. If you could have managed existing one, you could as well manage another two. So all this is not for a person like you. You do like this, follow idea No. 1. Go for one time settlement and finish this off via MCD, if you dont get MCD, you fight cases till the very end and come out of it.
