I have just completed 4 months of married life. My wife comes from poor family, all marriage expenses were paid by us. Soon after marriage i come to know that she does not respect elders and she always comment on people around me. I found my wife whatsapp chat with 3 or 4 guys (adult chat). one guy using abusive (Disrespect) language against me through his text. they shared personal pictures and selfies as well. By observing their text i found that my wife has crush on them. I asked her for explanation w.r.t those conversation, she simply said that these are casual chat. Through her conversations i found she using bad language against my mom as well as my family members. I took her mobile phone (smart phone) and bought another normal phone. Her sim is postpaid , bill paid by me from past four months.
How can i deal with this issue. i don't to want to live with her any more. is it possible to seek divorce from her. If so how can i deal with this issue with out complication. Can i file defamation case against guy who comment on me through whatsapp chat. Is it danger to have her smartphone with me as a proof.
