I don't want divorce my wife wants it

Hello Experts, I was married (court marriage) which was an Hindu marriage, ours was 2nd marriage & inter-caste. Things were going well for about a month an my mother suddenly got too ill (as she is diabetic), so having a 12 hour job I can't stay at home and work at home and take care of my mother, so my wife and my father (he is also too old) were only to take care of her, so the day came when my mother asked my wife to cook, but she couldn't. she asked her to help her (my mother), but again my wife kept on giving excuses & she did damaged some utensils and these things kept on repeating day after day, I just ignored all 6 months went, & suddenly she quarrelled with my mother & then i couldn't remain calm and i slapped her, she called her brother and went her home.Now she wants divorce, and i don't, i tried to explain her family that it was a mistake but they want divorce. What should i do? If she forces divorce then do i need to pay alimony? I have too many loans on my head. Pls help
