Smoking hookah!?

Monica • One happy mamma! 😍 💙👶🏼
So me and my boyfriend have just started  TTC #1. He has smoked hookah for over 2years me only 10 months.. We talked about how hard it can be for some with trying to convince being a smoker. So we decided to smoke twice a week. Well we only have one day off togetger so today I decided to leave work early to surprise him and he is smoking.. So now I'm wondering how often he dose that when I'm gone.?. If I have a right to be mad.?. And if I should take it as a sign he isn't all in it like me.?. It's not like he had a bad day he has only been at home and nothing is picked up.. Also the other day I came home and noticed he did smoke but I just left it alone Cuz the day before that was bad for him.. I could really use some advise please.
