Cheatinh and Fraud

I have been in a relationship with my boyfriend for the past 2 years.. The relationship was going very fine.. sometimes there was ups and downs... related to girls coming between inspite of all we continued our relationship..we have been in a physical relationship as well based on his promise of marriage..later once or twice he told me that our relationship is not pissible based on the caste problem.. but then again he promised that he will defntly marry and make me the one his mother wants... Based on this we proceeded our relation.. infact he used to ask for money from me every month... and i use to give it... Very recently i came to know that he is cheating on me with another girl.. taking money from me and spending on her...i almost have given 15k to 20k I complained to his family member and coach.. His coach is trying to help.. But his brother is like "did u ask our permission before getting into a relationship or having sex" He also mentioned "my brother can have sex with 7 8 girls leave them play with their feelings and come out.. where is the fault?" Let me also tell.. previously during all the problms btween us.. his brothr knew all.. his brother did tell me that our relationship will not be accepted by their family even if he accepts... But i was in a relationship with him so based on his words I trusted him He is from a punjabi family and me from a bengali family..he lives in siliguri and i live in kolkata... As he is a bengal cricketer he comes to kolkata to play... What should i do?? Am broken enough.. landing in hospital from last 6 days by attempting to die as i could not take the betrayal nither the mental torchur by him.. How should i legally proceed??
