dowry and harassment case against whole family

Hello, My Elder brother's wife filed fir against us and the sections in which she accused us are following: 498a, 354, 3 , 4 . The case is mostly based on dowry and torture but in the case she also mentioned specifically about me harassing her multiples times and also made her mms in which she was changing her clothes. They married last year in December 2018 and she only lived 2 months at our home due to her studies. All the allegations of her are false. Only thing in the case that concerns me is my sister-in-law's relationship with me was very strong and we were talking on whatsapp alot, sometimes whole night secretly. We were talking like typical bhabhi dever things. But sometimes in the messages i commented on her undergarments. But she took all things normally and she was enjoying my flirting style and stared flirting to me too like sending flowers , hearts etc. My question is i m in big trouble for harassment ?
