I've started planning my escape 🤐

Let me start this off by saying I am 6 months pregnant and have an almost 4 year old by this man. I'm in an abusive relationship. Physically abusive. My boyfriend has choked me 4 times since I've been pregnant. I've been wanting to leave him for some months now but when I try to talk to him about options and basically just tell him I'm not happy with our relationship anymore he freaks out and chokes me. He physically will not let me leave. So, I've decided to just pack my stuff, take my daughter, and leave while he's at work. 😞 I really don't know what else to do. He won't let me leave on good terms..
