My girlfriend made false promise of marriage and make phsyical relation with me and the just left me

A girl purposed me last year in month of may.she was my classmate in 11th and 12th class. And we are just friend. After passing 12 we don't contacted. Last year she make contact with me on whats and facebook. Then she purpose me on facebook( i have the proof as screem shots)at the time means last year she is 20 year old and i am 22 year old I try to refuse her but she tryed so well and perfectly by makeing so many promise like she will marry me and she will leave her family. But i always told hwr that i am just a student, i didn't belong to you relegion ,your parents will never agree on this.etc But she always give answers and say this that she want me only at any cost for life time. It was my first time that i make phsyical contact with a girl and after we kissed first time i told her that if she juat like me don't love then we should stop on this point. But she always says that she marry me and then one day we are on my bed we doing foreplay and underssing each other and then when i was naked and she was just wearing her panty she grab my hand and told me to stop .she says that she don't want to do vigainal sex at this time and i stoped to respect her feelings. But i already told her about my self and emotion and then i can't leave her after this because this all thing means for me a lot this is not common for me tats why i never do this with anyone. After our foreplay or phsyical relation one day she just told me that she not feeling god and suddenly she told that she can still leave her mother brother but her father will die so he can be with me anymore and this type of excuse which she already denny when she purposed me and i told this all to her.(call recordings) Now problem is that i am feeling depressed and fighting with the feeling of used cheat and so many emotions ,negitive thoughts and other thing are diatrubing me my daily life study and everything. 1. I want to teach her and girls like her a leasson. 2. If its possible i want her back. 3. I want to punish her what she did with me ,myself,my feeling or love ,emotions and my mind I readed if a boy do the same then girl can file a FIR but LAW should understand that we boy also have real feeing, emotions and we also hurt when someone use us or cheat us. Please tell is there any possible way to teach her a lesson and girls like her. I have all the screen shots off her promise and purposal and call records of her life time.promised and trust. Please contact me on my email: [deleted] I have some savings around 1 lakh.if there is a ways i will proceed.
