My husband won't brush his teeth

So this is pretty gross. But please, no bad comments and stupid gifs and all that. I need advice. My husband won't brush his teeth. He will do it once in a blue moon, I haven't kissed him in months. When he talks, I tell him it's gross because his breath smells. In the morning I tell him to brush his teeth, and he says he's running late. Or he just says "I did" at night, I tell him and he says he's too tired or he will later because he "might have a snack" the thing is, even when he does brush, its for like 30 seconds. He just puts the brush in, brushes for 30 seconds, spits and rinses his mouth. He won't floss. I have a water flosser, so you literally just put it in your mouth and it flosses for you. His excuse is that it "takes too long" it's 30-90 seconds depending on how much water is in it! I literally try everything to help him and get him to be better. He always smells because even though he showers daily, he doesn't scrub down there right. I can't give him a blowjob because of the smell. He doesn't wipe his ass all the way after taking a shit. It's disgusting. I have had SO many talks with him, literally. He says he will stop but no matter how much I push him.. he doesn't get better. We are supposed to be trying to have a baby but I told him this morning if he cant take care of himself, I won't and chances are we will get divorced because I can't even kiss him. His response was "I'll brush my teeth more. I shower daily. I wash down there too." But I hear that all the time! Ugh.
