Would I be wrong to breakup with my boyfriend for this reason ?

Many of you saw my post yesterday . I basically said that my boyfriend has had bad hygiene lately and it’s been bothering me and I didn’t know how to bring it up. I ended up getting a bacterial infection and he admitted that he hasn’t been keeping up with his hygiene . (And his breath is always smelly because he has braces and he always has food in his teeth) He said it’s because he’s been stressed . Ive been there before , so I definitely understand and I’ve been patient but if this continues I’m thinking of breaking up with him because hygiene is just a deal breaker for me . Would I be a prick for doing that though ??
