Hi, I am not a qulified person, but sometimes words can change things. After reading this post I was little surprised actually shocked. You are in a situation where you are literally hanging but you don't know what you are holding and when it will fall off. I just wanted to ask soemthings which I want you to think, may be these can help you to come to conslusion.
APP can personally help or guide them, there is nothing wrong but he/she can't represent your husband.
1) I think you met with you inlaws and husband after filling DVC for compromise? why is it not before filling DVC case? You want to use it as bargaining tool scaring them? If this is your story then I am really sorry. You also mentioned that they filed it HC, I see their confidence level. Are you doing correct and your allegations correct in your DVC? --- Think about it.
2) People go through lots of tension when a case is filed like DVC not even spending muchtime together he may be trying to protect himself and his familiy and asking you to sign their conditions. There is another face to it - try to defame you (experts can drag this case into his favour also even if allegations are genuine). Its your trust with which you need to make a decision whether to sign it or ignore it.
3) To add to above point - why do you want to move with your relation after filing DVC? its just an advice, take it to law (family matters) only when there is injustice and its harmful for everyone. I don't want to judge you but I THINK YOU DEPENDING ON YOUR PARENTS TO MAKE DECISION NOT ON YOUR OWN FEELINGS. This will be very dangerous, you husband might be doing it to safeguard his family but might also want you back in his life. Can anyone gurantee that you or your husband get better relation than this? if you wish you remarry after divorce?
4) If your allegations are correct then I would say goahead with your DVC, but if they are wrong and you can't prove it in court back off and rethink as it will for sure defame you badly and your future. Think about reconsilation with your husband if you trust he will look after you properly. Don't rely on your parents words, trust your feelings. You are the one who has to live with him, he may take care of your than you think. Not sure where mismatch between you reevaluate it.
5) You mentioned he is talking to you for hours together, it clearly tells his intentions that he wants you back but with some safeguarding options. Trust will come back if both of you are giving importance to your relation and care for each other. I guess trust is broken from your husband due to your act going with DVC which needs to be healed, and it will done with time. No one stops you from putting onemore case even if you sign anything but for him this one needs to be closed first to give him confidence to restart on this relationship.
6) If he uses this contract between you to defame you then no one has to tell you or guide you, you know what to be done.
TRUST is very important in relation, its not who is right or wrong what is important is rebuilding TRUST. As you mentioned, if you agreed that its your mistakes in front of their relatives just to regain control over relation. I would say what you are doing is not correct, what makes a person GOOD person? living truthfully. If you really think your allegations are correct and genuine fight back, that way you can live with pride even if you loose. But if your allegations are wrong and won over your husband it will keep coming back in your life that much I can tell you.
I wrote it for you to think in all these ways and take a decision, I am not deciding anything for you. Would like to say something, if your husband is still talking to you for hours and hours I see his eagerness to rebuild it even after DVC. No man does it after his own wife defaming him, i can guanrantee. How can he build trust again on his wife? Atleast don't go through your parents guidance, you lived with him do you know him better than your parents.
Think again, is DVC case correct?
Hope you will find answer to your issue quickly, All the Best for the step you are taking. If DVC is not correct and your allegations confess infront of him and others. This will ease you up, and one morething burning harathi on your hands just for sake of something will make any husband go through lots of pain.
You name me if you like my advice. (Please remember, I am not judging you in my above post)
