1. why you want to go for this we do not know but without the required facts it cannot be adviced
2. it is not fair but as it seems that you already decided the step means without proper advice you may land in different stress
3. so first meet a lawyer if you does not want to disclose the facts
4. by meeting personally and discussing with a lawyer you can share your query and also you get correct advice and any time we are here to give you advice legally
5. you can file divorce through a lawyer or self by party in person with a petition well drafted legally and ensure that all the steps come in order and as suggested if your husband does not appear even after court notice to attend, court will see to some hearings and finally you will be granted ex-parte divorce decree and after that 90 days time limit will be there for your husband to appeal against the said decree and if does not object or appeal against that order then you can happily marry another person
