Wife cruelty against her husband

Following are the points for harshment against me(husband) having a class -8 male child. 1. After came from office or by alone anywhere, she tell her son that he has engaged with a women having sexual relationship. After that she quarrel with the same. she always aim to misguide our son about me by always saying that i pay Rs 50000/-per month for that women. Although in last 18 years she never find any evidence.I tried to council her with my office staff as well as apartments members but no change. 2. Assume that i have multiple relationship with girls and having sexual disease so she refuse to have sex in last one year. 3. The Cruel behaviour of a wife by always initiating criminal proceedings my family members with malafide intention, etc although my parents is no more. She always scolded my parents with a worst words 4. She ever taken interest for any types of academic towards her son so after office i used to sit for teaching. 5. Due to her failure in respect to take care in study and other activities now her aim is to damage our son carrier so that i will suffer. 6. She always threat like 'jail u and ur family member those are stay outside by Domestic violence case' so it is my request kindly give suggestion as she is completely mentally harsh me.
