Was I wrong for telling him I would want a divorce?

ma

back I made an anonymous post about my husbands hand smelling like crap. (Literal poop like really stinky) I wondered what the heck he was doing to make it smell so bad. (Like I know hes obviously touching it. Ew) I still dont know exactly what's going on because he wont really tell me. but we have since had MANY conversations regarding it and how unsanitary it is, and that if his hands still smell like shit, and he touches our baby, that bacteria can get on her and make her sick. And how it's hard to be sexually attracted to him thinking about his hand in poop. Well I found poop on our WALL the other day. On THE WALL next to the toilet. I calmly called him into the bathroom and asked him to explain how shit got onto the wall. He responded with a shrug and said he would clean it up. I told him it was disgusting, and that this really needed to stop. Well today he took the baby out of my arms to hold her, and I smelled shit on his hand and i said he needed to go wash. I said I couldent believe i had to keep having this conversation with a grown man and that if it continued i would be asking for a divorce.... am i wrong? How can I raise my baby around that?
