Greetings,
Your Husband cannot stop you from entering your matrimonial home as long as you are married to him,
1. You may approach the local police station at Pune for help and get an entry in the house.(Police normally call the husband and reason out with him, sometimes by explaining him about 498 A in detail)
2. If you don't want to try the first option and if you don't want to come to Pune then You may file DV case at Delhi and a) pray for residence order for staying in Matrimonial home and b) Protection order restraining him from alienating the property.
3. Contest the divorce case on Merit and claim compensation.
4. If he ever threatens you please record the conversation and lodge a police complain.
