I think it's important for you to know that strangulation is an indicator that your life is at risk, he could kill you. I'm not trying to scare you, i just want to emphasise how serious this is. https://www.policyforum.net/red-flag-homicide/

I went through domestic abuse for almost 4 years.

Create a support system for yourself, talk to family or friends you trust.

Report this and gather evidence if you can. My biggest regret is not protecting myself more by reporting what I went through to the authorities. You need to protect yourself.

Contact women's aid or some form of support for solid advice and counselling.

Wishing you all the best, you will be okay ❤️
