I agree to both @ Sanjeev and @ Ashish; BUT
When the Appeal is presented before HC at that time pray for sending the parties to HC mediation and get over with somehow managing at the end a 'divorce' via some realistic / un-realistic mutual settlement if that is what was hindrance till lower Court stage all these wasteful years of either spouse.
If that is also not agreed by her side then admit SLP before Hon'ble SC and again submit there to send parties to SC Mediation there they have worldly wise seasoned mediators who will hear both sides with grandmasters vision and 'fix it" and make her / her side understand there is no point living life without “divorce" as there is complete breakdown of your and his marriage.
If that is also not possible then to all your three questions I concur nothing much can be done and you and her lives are spent living apart rest of your lives with no solution until some divine bolt out of the blue strikes and adamant party bends knees finally.
Well finally if that was also was not one of the visions meant to happen, then if you are male then go get re-married and quickly produce a child out of such “cheating in marriage”. Now what will happen is “she” ought to put a complaint but then Court will see the previous histories of parties right from trial Court to Hon’ble SC and also hear a weeping “illegitimate child” in Court room tagged by ‘humble looking saddened face second wife” that is where softer “punishment” will be granted with decree in divorce in exasperation by Lordships (to protect second marriage and THAT child) and case laws are there to substantiate this summery for men’s eternal solutions to problems they themselves created to begin with!
Flip above summery solution offered to men’s having grand experience with brush with divorce Laws for 'n' number of years with no solution in hand, now if you are a simpleton woman and “he” is adamant not to allow your divorce dreams till date then simply run out of the HOME and live with another man as per your ideal dreams. Let earlier husband file a complaint case. Now ld. Court will respect your “new gained status” and shall not only grant decree of divorce from first husband and tell you proudly “you are not a consumer product” to be retained for eternity by first husband! Case laws are there to substantiate this summery for woman’s solutions.
Summing up; that is why I say here, it is better to seek decree in divorce than living a life of 'separated tag' as such 'status' is not the solution to respective spouse long term marital problems and it is not that I advocate 'everyone should be divorced" and/or “I encourage adultery/bigamy here” and/or “I advocate live-in here” which selective few time pass writers here often do mischief of misconstruction of my practical (based on already decided case laws) based solutions thereof.
Now if anyone of you pundits and punditians have a legal as in “case law based solution” to the eternal problem of either spouse other than the two I pointed at please note I am all ears to just hear them out and correct my alleged Igyan henceforth J
PS:-
Some years back the then Lordship Hon'ble Katju commented "look left - look right….." and thrown out a Air Force officers 12 years old divorce blues out of the SC Court room No. 6. I still respect his then wisdom and still remain inspired by his grand masterly comments in open Court Rooms on and off, BUT I was thinking, I would love to politely seek "social" remedy the next time I stumble upon the then Lordship in one of the Iftar parties in Delhi who now is a public figure as "solution out of the book" to 1 till 3 questions of alleged queriest in generic terms as the clear legal answer to queriest three questions are is in big NOs' and may submit - is it not "cruelty" to bond spouses eternally when either or both donot want to remain bonded in marriage vis-à-vis the alleged solutions I offered which were infact based on decided Case Laws of various States HC's as in above which can be controversial bare reading wise but when there is no other clear solution in hand what incompatible spouses are supposed to do in so called social India !!!!!
