AIO? Husband tried to choke me but didn’t do it "as forcefully as he could have" so it doesn’t count?

I've been freaking out about this for a while. I keep bringing it up with my husband but he tells me I'm being over dramatic. He also told me it's my fault for mentioning that I wanted to be choked and weeks ago (i meant during sex)

Backstory: I was in therapy and embraced with therapist. It was the worst mistake I've ever made. I told my husband and he's been really upset for several months (understandably so). He was having one of his yelling cursing tangents (i let him so that he can get his frustrations out) and sometimes i zone out when it gets to be too much and start scrolling on my phone to get my mind off of what's being said. I stupidly smiled at something I read and he LOST IT. He Jumped on top of me and hit me a few times (no bruises just a light raised mark from his hand) and then put hands arms around my neck. I thought i was going to die for a few seconds but he loosened his grip pretty quickly

My husband says I'm ridiculous for being this upset about it. Am I overreacting? He had a good grip on my neck but it didn't really cut off any of my airway or anything. I guess i was just more freaked out than anything and I commonly overreact to things like this. I was contemplating leaving but I don't want to feel like I'm making a spontaneous decision from something that's not that big of a deal. Please answer honestly and with an open mind – maybe it was just playful and I misread it? Preferably Id want to hear from me have been in this situation and was angry but didn't plan on actually hurting your partner
