If you appear before the court, the opposite party may demand court to direct you to deposit your passport before court and you will be even restricted to travel abroad during the pendency of criminal case against you, so better avoid visiting India, nothing will happen if you dont come.
The women these days think that they can do anything to the their husband and in laws having this legal weapon called 498a etc, but the fact is that will appear dreadful only in the beginning and it will get diffused during trial proceedings and they will not be able to prove their alegations during trial proceedings.
