Defend or relieve from harrasment from wife parents hate our love marriage and now she too with them

I tried to convince my girls parents for marriage but they have refused for it showing my lowe caste. They I made a meet with my parents and said the girl I love my parents and I can't leave them at any cost, even after you come, we all should live together and apart from these I don't need anything, she agreed and decided a date to come off from home, at that day I took her to my village and got married and her parents came and convinced my parents to marry again, then we had made it again without taking a single penny. After few days, she started saying to be separate! I refused, then again tried, I refused. Later she was carrying, then I made all the payments of hospital and till my baby birth, after that she again troubled me to come out of home for which I refused. She left from my home and dropped a complaint against me in she team or bharosa, for which I attended the counseling and cleared my stand of not leaving my parents if she can come I'm ok, Later after few days, I got the copies of complaints filed by her on harrasment for dowry and blaming as a gambler, I have a debt of 8 lakhs and forcing her to get 5 lakhs money even after they gave me 7lakhs and 18 thola gold as dowry and forcing her to withdraw complaint by goondas. Then I Spoke with her and did not asked about this details and took her to the same team of bharosa and asked in front of them about dowry and made her to sign a letter in which it is clearly mentioned that I haven't taken a single rupee nor gold from marriage till date, this letter has been read by councillor infront of her and she agreed the same and signed in front of she team or bharosa councillor but did not utter a word about the complaint which she made as false. Till date she don't know that I have the complaint copy and I know all the false allegations. How can I be secure in this case, I don't trust her not her parents! I didn't take a single rupee nor I don't ask about that. But I want to be safe for my future, help me out sir
