Why do guys feel the need to be right all the time!!??

He loves to tell you about yourself but it's world war 3 when you tell him about hisself. He always right and never wrong omg. After he make his point your answer going to get ignored. he argues with me purposely but when you on his ass about getting your point across he dont wanna hear it. He got pissed off and chNged his number like a 10 year old and still heard my argument through whatsapp and anything else he on. I dont play games with people. in his past relationships girls let him do whatever he wanna do to them. everybody know women like to be right anyway lol
