1. Don't fall for their 'I Love you yaar!' quote
Men have this habit of replacing a simple 'thank you' with 'I love you'. Their mind is just plain and dull, they won't understand how a woman sits down all the day to interpret... What did he mean actually?
A genuine guy who's falling for you would rather avoid saying 'I love you' not because he doesn't feel like but because he's afraid to lose you for its consequence.
He will take his time to say it, so don't go out blaming that he's not serious. If he's really into you he would instead make sure that the next time you two meet he's ordered you favorite cuisine or got tickets for the movie you had been craving to watch so that he could see you the joy on your face closely.
