My wife is not staying with me

Dear Sir/Madam, I got married two years ago. At the initial stage of my marriage life (after 1 month of my marriage), my wife started to chat with her friend (to whom she wanted to marry) in whatsapp. I said to her 'don't do like this and it's not moral'. She felt guilty as I know about her chat. From that time she started to harass me and got abortion. After abortion she was not willing to come but her family members forced her to stay with me. Finally she came and started to harass me as usual. After one month she left my home without communicating to me and my family members with all her luggage (it was happened after 9 months of my marriage ) I asked her so many times to come with me. But she didn't come and asked me to give divorce. She is not willing to give divorce but she said "you will go and apply for divorce if you want". What can I do in this situation? Please suggest me. Thanks in advance.
