Is it cheating? Lying? Being deceitful? Gaining weight loosing weight? Personality change?
Most Helpful Guy
Probably the biggest thing is to be far too entitled. Like if you have a list 100 items long of things you expect him to do before he gets that pussy. Or you use sex as a weapon. Or if you think your lady parts are worth more than his man parts. Or yes, cheating on him when you expect him to be faithful to you. Hypocrisy as a whole is super entitled. It couldn't exist without a double standard in the way you treat him and the way you expect him to treat you. These are all really symptoms of the same problem which is an inflated sense of self, or a deflated sense of your respect for him. Or both. Neither one is attractive. In fact, its not just me who feels this way, in a study done on photographs of people, men found pride the least attractive emotion on a woman, with a blank expression, shame, and happiness all rating above it.
Lying i'm sure would be a turnoff for anyone in any kind of relationship, and gaining weight probably won't help. But neither one of those is a deal breaker in small amounts for any guy, provided he's not super picky. Most guys can accept that you're only human and make mistakes. What they can't accept is if you seem to think for some reason that you're superhuman and never make mistakes.2
