Wife has taken child away and not giving me equal rights

Hi, I am 39 years old. I have been married for 6+ years. We have a 5+ year old daughter. It was an intercaste love marriage. At present my wife is literally bullying me. For the last 12 months I was living in a different City and my wife and daughter were living in her home town (My adopted town/ I owe a flat in this place but we were living in a rented apartment as the flat was not ready). This was purely because of work purposes. I was travelling to and fro every second weekend and things were taking it's toll, so I decided to quit my job and take an opportunity in her home town. From the moment I came back she has acted weirdly and have told me that she does not love me and do not see any future for us. One day they (the girl and family) came to our place (rented house) and started putting all kind of allegations on me and my family. She started quoting old issues (blatant lies) and started to talk crap. This was because through channels we found out that she was having an affair with someone. Unfortunately I do not have concrete proof of same. Anyways after that day we (me and my parents who were visiting me to resolve this issue) decided to leave our rented house and move to our own house. Currently my daughter is living in the rented house with her mother. After a few days her father suddenly called to say that we want things to be normal and maybe we should try counseling on the condition that we need to first talk about the affair. I agreed on same and it is been almost 6 weeks but no progress. In between I am getting to meet my daughter for a few hours on some weekends whereas she is taking decisions like weekend out of town with daughter without discussion. I am missing the time with my daughter as I am not getting the chance to take her studies and impart fatherly duties such as getting her ready for her school . I am traumatized by the separation from my daughter. She maintains that she does not want to return to this home as she cites that she is not in love with me anymore. I am so full of anguish against her and her joint family that i have lost any feelings for her. She belongs to a rich family and has lots of money to spend on herself and have threatened us with domestic violence and caste cases. I would like to evaluate my options to get out of this wedlock at the earliest as I have no intention of staying with her anymore. Also a word of advise on my daughters custody will really help me.
