Am I being dramatic? Feces and a newborn

I have a newborn and my bd has a new girlfriend. The issues comes when this girl constantly smells like weed and lives in a house full of feces on the floor. I ended up on her page and she posted her guinea pigs room and there were hundreds of feces on the floor. Now I feel paranoid thinking he’s going to come around touching my baby reeking of weed or microscopic feces. Am I wrong for feeling this way?
