Initiation of divorce & handing over belongings

I have been married for 7 years now and have a year old kid. My wife always suspected me as I am a very amicable person and would get along well with all kinds of people. Her suspicion escalated and she accuses me of an extra marital affair with one of my colleague. I sent my wife away from my place to her paternal home to avoid any complications during pregnancy and risk of life to my unborn child. I thought it to be mood swings during pregnancy but despite proving her accusations to be wrong, she had harassed my colleague, her kids and me with abusive and derogatory texts. I have been a victim of mental cruelty for the over 2 years now. we are living separately for 17 months now and she has my kid and is working in an MNC as well. I have informed her that I cannot live with her any longer after defaming me in my family, office & neighborhood. She has taken few of her belongings and others still remain at my residence. Can I file divorce basis of mental cruelty and 2 yr separation(including pregnancy period)? Also can I send her belongings in private transport before filing divorce? Is there a way to file a no fault divorce & to make her agree for mutual consent? can I seek custody of my 1 yr old girl now or only after 5 yrs?
