I have come across many cases like this. I can understand your problem at this stage. It is unfortunate that you could not lead a happy married life. There are some incidents that happen in your life and those incidents are so strong that they change your DNA. At times, despite our best efforts, life takes a turn for the worst. We may have wanted different things from life, but life’s got its own plan as well. A bad marriage is something which nobody hopes for, but at times, that’s exactly what we are given and forced to face head on. Marriages are hard. Divorces…even harder. Nobody enters marriage thinking about a divorce in the end. If some are unable to cope with the harsh realities of marriage, the only viable option in front of them is to approach the Court and seek legal separation. Marriage doesn't guarantee that you will be together forever, it's only paper. It takes trust, respect, friendship, faith and understanding to make it last. Moreover, a relationship without trust is like a car without gas, you can stay in it as long as you want but it won't go anywhere.
You can take divorce on the ground of mental cruelty and many other grounds. You have to take a call now. I would suggest you file a mutual divorce petition. Divorce by Mutual Consent means when both Husband and wife has agreed amicably amongst themselves that they cannot live together anymore and that the best solution is to Divorce, without putting forth any allegations against each other, in the court of law, than such a Divorce petition presented jointly before the Honorable court, is known as mutual consent Divorce, it is the quickest form of divorce in India. Mutual divorce proceedings take 6 months to settle.
If have an anticipation that your wife will file false 498a then you should immediately obtain anticipatory bail. Under Section 438 of the Criminal Procedure Code there is a provision for a person to seek ‘Anticipatory Bail’. This means that an individual can seek or request to get bail in anticipation or in expectation of being named or accused of having committed a non-bailable offence. Anticipatory bail is meant to be a safeguard for a person who has false accusation or charges made against him/her, most commonly due to professional or personal enmity, as it ensures the release of the falsely accused person even before he/she is arrested. To get anticipatory bail the person seeking it, must approach the Court of Sessions or the High Court and citing section 438 of the Criminal Procedure Code as well as giving proper reason, apply for it. If the court, based on a number of conditions and the nature of the case, sees merit in the petition the bail is granted. Hence if and when the person is arrested, he/she will be immediately released on the basis of the anticipatory bail.
You can collect all the evidences like audio, video and other documents to prove your say.
At last I just want to say that divorce isn't such a tragedy. A tragedy is staying in an unhappy marriage.
