Suicide threats by wife- contested divorce

I am married for 7 years and living apart since 4 1/2 years. I have filed for divorce in Rural Court of Bangalore, that is where the jurisdiction lies. However, the woman is denying to give divorce and is insisting that i take her and the child with me to Delhi which is not possible for the following reasons:- 1. She is an egoistic person, who for anything and everything threatens to commit suicide (but i dont have any recording/picture/text/voice of it) 2. she attempted suicide for the thrid time and i decided to divorce her. 3. she cannot cook 4. she picks fight over money. 5. she does not respect me. 6. she wants to come to delhi and live with me but thats not possible from my end as i cannot risk getting her here. 7. she is earning a good salary. 8. she and i are opposite personality people who are not happy with eachother.neither does she nor her family respects me. 9. she is living with her parents in their home. I requested her for a mutual consennt divorce but she denied and therefore i had to unilaterally file for a contested divorce. she has opposed the divorce petition and has filed for maintenance application. My question is- 1. how to prove mental cruelty like suicide when i don't have evidence for it. it is a fact that i and she knows. 2. how to strengthen my case? 3. on what ground can i deny her maintenance, 4. there is a 5 year old child.. will we both share child expenses equally? Also, looking for a good and efficient divorce lawyer in banaglore to fight my case efficiently and expeditiously.
