Query for Rape case 375, 376, 354 IPC

Hi There is a girl (Fresh non practicing Advocate). She got raped by Professional working doctor (friend earlier) multiple times. Girl was under depression and trauma during this incidence. She didn't realise about her mental condition but she WhatsApp to her rapist that she is feeling to commit suicide. And she kept chatting and complaining to rapist why he did this to her? He was a married with two kids. This happened when his wife was pregnant and in hometown for delivery. At that time doctor called patient friend to his house for suture removal and raped her and kept calling her pressurising her and said to her out of his sick mindedness that tu merse jitne bhi sawal kar Mai jawab dunga. And he kept repeatedly raped her for some days or months. And kept writing sorry on WhatsApp that - "Mai ek pavitra ladki Ki zindagi barbaad kar raha Hu I remember all my f**king bullsh*t". etc etc. Now its been more then two years to this incidence and girl is under psychiatric treatment and under heavy trauma. The rapist later started pressurizing her for marriage and kept recording her soft conversation but did not record his promise. He even said over call that wo shaadi nahi kar sakta shaadi ek Pavitra Rishta hai in order to record it. Where girl insisting. I want to know what if she files complaint now after a long delay and under her this mental condition what could be the consequences and what worst girl victim can suffer ? Now victim is married but under psychiatric treatment and husband is ready to support in case. Husband married after knowing all the truth about her rape and mental treatment. Will girl suffer if she files case ? Later Rapist told his wife multiple lies by presenting it as an affair and she threatened victim not to file complaint otherwise she (victim) will loose the case and she is a high court lawyer and put her into false cases. And will present all her recordings to society and court. Will girl suffer if she files case ? What could be the consequences ?
