Am I wrong ? (Long story)

First, let me apologize for this being so long. My boyfriend smokes weed.. Everyday. And I hate it, when he doesn't smoke he's a different person and we argue. Today, was supposed to be a celebratory day because of my new job offer, we were out and he asked what I wanted for dinner.. Me being a lover of crabs wanted that. He tells me that he wants "something good but something different" he said that every restaurant we go to are the same, from ruby Tuesday, long horn, outback, etc. He didn't want to go to a fancy "burger joint" he tells me he wants soul food and I tell him that I don't know a place. Then he says well it doesn't have to be soul food. So I said if all restaurants we go to are the same maybe you want a different culture, so I suggested Indian. He took that as me being a smart @ss and went crazy .. I started to cry because he's getting angry and saying smart things. I was just suggesting places. It's 100% in Philadelphia and I walked home 7 blocks because of this. I think this relationship is toxic of he is only normal when he's high.. But was I in the wrong for him to flip ?
