Gbs test and hubby....rant!!!

We went to bed knowing that this mornings appointment included the gbs screen... He was fine with going with me last night. .well this morning hes throwing a fit stomping around" i dont understand why i have to go with u to get your pussy swabbed bla bla bla" i simply said u dont have to go he insisted on going but now hes waiting in the car as i type this out naked from the waist down waiting at my appointment.... Immature right? If he cant handle this will he be able to watch me give birth??! 😕 i even told him not to come if he didnt want... ? Ugh... Youd think an almost 25 year old man would be more understanding and mature..guess not... 😡
