Someone please help me know what to do...This argument was so stupid and I may have just lost my husband forever because of it.

We were watching a TV show, and in the show a male character was sleeping in a hotel bed with a woman that was not his wife and I mentioned something like “wow, I hate that every male character has to cheat”. Well, my husband replied with “thats not cheating” and I kind of freaked out a bit and asked him how that’s not cheating (I have been cheated on in the past by a man that’s not him so I have a little bit of past trauma when it comes to cheating) and kept questioning him about it to the point where I was getting so frustrated I started crying. Well, that was a last resort for him I guess; he said “I can’t believe you would insinuate that I would cheat” and walked out the door, saying he can’t deal with me anymore.

I’m so upset i want to die. I don’t know if he’s leaving me forever, and if I’ve ruined everything over a stupid tv show. If someone has any advice for what I could say or do to fix this, it’d be much appreciated. Also I’m so sorry if none of this made sense; I’m going crazy right now.
