Married twice but only to save myself and the girl, please advise

married a girl who was as old as my elder son because her brother in law falsely accused both of us having an affair,which we didn't.We were colleagues doing network marketing.She was just my downline & I had worked with 1000s of women before also,no special attention was given to her.Her brother in law had family grudges with her so he spoiled her name and tortured and beaten her in front of public. She kept a condition that I shhould marry her or else she will attempt suicide.I didn't understood what to do so I married her.My family disowned me and threw me from my home. I am living with her from 7 yrs now we have a daughter(5 yrs),but my 1st family keeps torturing me.They are mentally harrasing me for the property.I am giving 8kmonthly+3sacks of rice annualy.My son's are 28 & 26 yrs of age. My 1st wife is not filing divorce because she knows that whatever I am giving is more than enough. B4 taking the decision to marry this girl I told everyone about this situation.
