Divorce from a spouse staying abroad

I have been married for 12 years (Punjabi married to a Bengali husband) with 2 daughters aged 10 and 4 years. I stay in India while last year, my husband relocated to The Hague in Netherlands for a better job. Though he came back to India frequently in this one year, our relationship has not been great even before he left with almost no communication between us for mire than a year now. My in-laws stay in Kolkata and I stay in Delhi and my parents stay close to my place. I work in Gurgaon and my kids go to a good school in Delhi and after school stay with my mom till I come back from office. My husband told us to shift along with him, but that would mean that either I give up my job or of I find a job there, then my kids stay in a day care centre which I am not comfortable with. He sends money every month but apart from the monetary part, there’s no involvement and no physical or emotional relationship between us as husband and wife. I want to understand what are my rights / chances if I seek legal separation or divorce from him and what will be the process as he’s not in India? What will be your advice as a legal counsel?
