Wife 33F slapped me 34M after one month of wedding

I am 34M, married to my wife 33F last year in feb. I wasn’t fully aware of this before wedding but she seems to have anger issues. One night when we both were drinking, she got very angry and fought about why i asked her to pay half in our wedding. We split all expenses in our wedding equally. Suddenly she was on top of me and started slapping me for 4- 5 times. I was utterly shocked. I didn’t know what to do so i went in washroom for sometime. She also broke glass. This is 8 months old incident. Since then she has been fighting over very small issues and i am ignoring as breaking marriage is not easy thing to do. She has embarrassed me in front of my friends too. I am very sad that I’m living with same woman with no fault of mine. Somehow she also manages to put all blames on me and now I’m confused if it is is my fault. Is it healthy to stay in this relationship? It is also affecting my work, I’m sole earner in my family and she doesn’t seem to care at all about financials and peace at home. Please advise. I’m also very much worried what happens if we decides to separate knowing indian laws. Can someone guide me what are my options legally ?
