Is it his job? PMSING

Im pmsing super badly rn and ofc it’s up to me to hold it together and still be an adult and do what I need to do. but whenever I get like that, I get moody and get really emotional to my bf, he will argue back with me. I told him dude this is gonna happen sometimes and all u gotta do is say it’s gonna be okay, nows not the time to argue. im unstable when my hormones are like this so whatever I say isn’t gonna be rational at all, so like I just wanna know ladies…. do y’all expect ur man to know how to handle this or at least tell him in advanced like how pmsing works cuz I don’t wanna be toxic or bossy to my bf or tell him what to do or how to handle me when it’s my own responsibility but as partners who may live together one day he needs to expect this.
