extremely unhygienic husband

ladies, I'm in a bit of a mind mess at the moment. I have an extremely dirty and untidy husband. he is very unhygienic. I have been ignoring it for years but today I have just had enough. came from work and saw my dress and scarf in the walking closest and saw that he had cleaned his boggy on my scarf and party dress. it was literally covered. I'm so disgusted that I didn't even want to have dinner. he bits his nails and spits in the room, he doesn't flash and never uses toilet brush. my god the list goes on. not sure. it's just the two of us that lives in the house and he says he hasn't done it. I hate the fact that he won't even fishing**** admit his God damn mistake. please advise me. I'm losing my mind. feel like I'm going to explode from the anger within.
