ms. swetal,
while filing S.125 cr.p.c., you must be clear about a few points. (1) Being a govt. officer and earning handsome amount, you may not get maintenance. (2) your husband wants divorce, but he cannot get it easily, so sent notice under that RCR section (3) you responded to that notice positively seeking mediation for atleast four or five times (5) he does not want cohabitation but divorce, so has not turned up for mediation. (6) FINALLY, HE WANTS TO BREAK THE MARRIAGE AND YOU WANT TO RETORE IT.
As this is the practical position as on today, you are filing S.125 cr.p.c., NOT FOR THE PURPOSE OF GETTING MAINTENANCE BUT INITIATE MEDIATION, SO THAT FINAL EFFORTS CAN BE PUT TO SALVAGE THE MARRIAGE RELATIONSHIP. The mediation under Section 125 is different to mediation which you tried to do when you received the notice. There is certain force in the former as that will be conducted by court officials. where as in the latter mediation only advocates without having any legal authority conduct. Further, in the mind of husband and his mother, there will be fear that if S.125 they absent themselves, there is a likelihood that S. 125 verdict may go against them and they may be forced to pay maintenance.
If you are not inclined to go for S.125 cr.p.c., you can also go for DV Act. In this Act also, mediation is the first step. In this Act, you can ask for the shared household and protection orders. In this case, for the mediation, certainly your husband and mother-in-law will come. The choice is yours - Section 125 cr.p.c. or DV Act. You read my first post, my preference is for DV Act as it is more deterrent.
