Gross boyfriend

I’m so fucking annoyed I’m constantly having to tell my boyfriend to shower bc he’s musty and to brush his teeth and wash his hair he’s 22 years old now like the fuck!! I’m not his momma and he does it only if he knows I’m around but if I’m not he won’t we been together 4 years and have been living together y’all I’m soooo annoyed and over him it’s not even funny.
