Fed up with daily fights and voilence.

Hi. I got married 8 years back.After the marriage there are frequent fights between my mother and my wife.They hate each other and never compromise with each other.Both keep their EGO on top.No respect for older people and no respect for indivifual.My wife dont want to live with family.She always wanted nuclear family.since my parents are old and not well so I need to keep them with me.I am always getting sandwiched between them.I always try to keep the bond between them but It never happened.Both of them are also not happy with me.On small diapute my wife has left the home and went to her mothers home town with my 3 years old daughter.She is not picking my Phones and not showing me my daughter to me.I requested her to come back and I will agree to all your points but now she is talking about mental torchure ,harrasment,Violance, mental harrasment bla bla that will take time.I want to get her back to my home Peacefully without involving any relatives.what should I do?
