Can my family approach my ex-GF to quash cyber crime cases against me

I used to be madly in love with my ex-gf who promised to marry but betrayed me by keeping multiple relationships, took my money and married someone else(illiterate). I could not bear breaking of trust and took revenge by sending her nude pics, making calls to her husband's sister. I went into deep depression and did all this so that she stick to her husband and let her in-laws family know her true face.My ex-GF and her husband's family has filed 5 cases against me assuming this girl is innocent. Her husband's father has commissioner influence.Cases are IT act 66,67a, 345a,d,506. I was caught by police and I accepted my mistakes( though there were no evidences against me to prov).Later I got released on station bail only when I showed the evidences(my pics with her,msgs). The police guided me not repeat and informed me that I may require to appear in the magistrate court for summons against me only once. Can my family member or anyone approach my ex-GF or her in-laws to quash cases?
