My boyfriend strangled me…

My Chinese boyfriend (I’m English) is quite possessive and I find he suffocates me a lot. It’s a new relationship and we’ve fought a lot due to cultural differences e.g. 3 months in he said he wants to marry me and plan a family and I’m barely past the “I like u” phase. Found he became quite possessive over time, gets jealous if I play sports with other men and always tries to play sports with me (even though he’s kind of shit and I find it boring playing with him cos he sucks). Anyway the straw on the camel’s back happened when he was having a shower and I got bored. So decided to hide inside his closet and wait for him to come out and boo him (I’m smaller than him). I’d done similar things like that before but usually behind a door or a wall, not inside an actual closet. He comes out of the shower and calls my name but obvs no answer. I’m laughing my arse off trying not to give away my position. He opens the closet and I go “boo!”. I start laughing as he was shocked and he started laughing, then SWITCH. He flipped his lid, grabbed me by my neck and strangled me for a solid 3-5 seconds and I was caught totally unaware. I couldn’t compute what was happening and I was chocking so bad. Eventually he lets go and I gasp for air. He then walks over to the balcony to cool down from his red hot anger and I use that as my opportunity to pack my stuff up and get the fuck out.

As I leave by the front door, he hears it go and runs out and grabs my arm but I manage to get away and call the lift. He lets me go and says it’s my fault because I overstepped the boundary of a joke and what I did was unacceptable. Wtf!? Thoughts?
