I have several friends who never lie about their marital status and a few who mostly lie about their marital status. According to me, people do this just because they want to flirt. There is no benefit of lying about marital status on a career standpoint. There is no use of lying for any other thing but yes, if a man will lie that he is a bachelor, then he will be able to find a girl really fast. The majority of these type of people is growing at a rapid pace in the society, some married people are using these tactics for sex and money but this is not a good thing because when a person will get to know about your marital status, you will not be able to handle the situation, as this will not only disturb your personal life but also your family life, especially marital life.
