I find most of the comments saying.....
1.Don't misuse law
2.Talk and explain your realization to your husband and ask for appology.
I also agree to these two points.But I don't understand "HOW"....if they are not talking to you.
Since I have gone through the phase as your husband is going I can give little idea what he is expecting.
1.He is not at all interested for divorce.
because ,If he was interested he would not have risked himself to come back to India on VACATION and get trapped in 498A or something.He could have applied the divorce in CANADA and in your absence he would have got that and get married to some other lady.You could have done nothing to him.
2.He is waiting for your appology and looking for you to come back.
He are few things you can do immidiately since you want to patch up and you realised that there was something you should not have done.
A. Send SMS ,Email and try to call him.But definitely do the first two.And keep on doing.
B.Send a letter written in your own handwriting in white paper addressed to your husband in registered post with AD.
Write all your feelings and all your realisation and your will.
Its your marriage and its your life.. If you have to go and talk...if you love him climb the mountain or go to the sea.if he loves you he will understand and will accept you..
only request .. Do it Fast .. before he leaves...and if you go with him to Canada .. considering him ( as you told) he is a good person.. then other member of family hardly comes into picture..
