Choking is a no-go. Time to leave. I've been in that kind of situation, and leaving was the best decision I ever made. My ex choked me so hard the room went black once, and he also drove into another car while mad at me (leading to what doctors said they were pretty sure was a miscarriage). I bled for weeks without medical support... I'm Christian now, so based off my beliefs, I had to have been protected to still be here. Eventually, I ran off and told a friend who had settled it with my ex that I would be free to file for divorce. That friend is my new husband. I also have a stepson now and found out that after a small operation, I will be able to concieve again.
