So my boyfriend has sort of "let himself go". He doesn't really try to look good anymore. Even his hygiene has changed..(not in a good way) I just feel like I should tell him this but idk how to go about it. He wears dirty stained clothes and claims to have just washed them and sometimes I can tell his teeth haven't been brushed (gross I know) but I don't wanna get rid of him bc of these things if I can change it. Any help?!
