In my experience, when you cry the guy drops everything he was saying and suddenly hugs you and holds you and comforts you. Regardless of the argument tbh, when I cried he would drop it and apologise... Eventually. Ok now I think back not everytime, sometimes he just left.
It depends if she is crying simply to get her own way and is not real tears but fake ones it pisses me off but if she is honestly upset then I would comfort her in most cases. However, if she had just cheated on me and I told her off for it and she start to cry there is not way on earth I am going to comfort her.
if it does not make any logical sense then yes it is total BS in my eyes.
for examples NOT BS : she cried cause i said something really mean to her BS: cause i was running lat for work and forgot to kiss her and say I love you by mistake due to my mind being on other thoughts
