Can I just leave divorce paper before escaping from India

I am married women since 5.6years without kids. It was mutual arranged marriage. 1st year I tried initiating the emotional and physical bond but never received same from my husband. I expressed my concerns many times about not having intimate relationship withhim and he always said he would try but never showed any efforts. Sadly I lead to an affair with other men between this lack of intimacy marriage. My husband found out and asked me to stop it. He said he is guilty and he will try but I see no efforts from him. Often I am upset or lonely and he knows it yet he tries to talk social and other subject but never try to talk about our messed relationship. I always see him trying to avoid our relationship matters discussion. He is good person but he don't fulfill my emotional or physical needs. It's been 4years now that we hadn't had sex. I asked him divorce but he don't agree and I don't see even in a future he would change. I am planning to leave my money and assets to him with legal NOC and divorce papers so he could remarry without trouble. I will be leaving abroad. My questions are: 1. Will he be able to force me legally to come Back to India once I am gone 2. Can I leave divorce papers and NOC for property saying I divorce you and I have not interest in the property that we buy together. without his signatures 3. Will I get any legal issues from Indian Ambussy to get work visa or to stay in the other country without his signatures Please help me understand what can be done.
