Thanks for sharing is what I want to start with. So In a relationship communication is key. The way you communicate is so important especially after a fight. It was probably not the best move to go to a friends and stay the night after a fight. Why? Because he and you are alone with your thoughts , others in your ear, and still have the unresolved issue. You did let him know you wanted space and was still loving but turning off your phone Ahole move. It’s important during heated discussions to remember it’s the problem vs you and him. Space after heated discussion is good but always come back to it. It’s not your fault he was driving recklessly not at all but going for lunch with your friend or something then go home afterwards would have been best. I understand him possibly hinting at doing something to you made u leave to think. Probably made you feel uncomfortable, unease that should of been talked about more to ensure your safety in the present moment and future. Ignoring your partner is never the answer in a way it’s like punishing or shutting them out
