I was joking around with my ex bf (idk what we are right now but i'm still very much attached) and it turned into this deep convo about our issues and why we are the way we were and it was going good until he said "brb i'm going to smoke" in the middle of it. This triggered me so bad and sent me into an episode. This is the second time he's done it, the first time i said "ok i'm going back to sleep" and he said "oh" "alright" and this triggered me even more i just ghosted him for days because i knew my reaction would be just anger and saying stuff i don't mean.  today it took everything in me to say okayy and not blow up. He texted me back and i physically can't reply without feeling like i'm going to throw up. I have no idea why that's so triggering about that. He mentioned he doesn't want to be around people who treats him different when high so i've been trying my best to not seem bothered out of fear he doesn't want to be around me. i feel selfish and like i'm triggered for no reason and it wasn't that serious but i just can't reply to him now.
