Avoid exposure: You should ask politely that he not smoke in your presence, and you can minimize the second hand exposure. You didn't say what he is smoking in the hookah, but both tobacco and marijuana second-hand smoke should be avoided in pregnancy. If he doesn't respond, you need to demand that he not do so, and you should consider staying away from him when he smokes if he won't cooperate.
