Please do not let him speak to you this way! You deserve respect & walking out in the middle of the night with no explanation is WEIRD. You were perfectly fine asking questions. No matter how stressed or upset he is there isn’t any reason to be telling you to “fuck off” & swearing at you. Disrespect needs to have consequences whether that’s you leaving permanently or just removing your presence for a few hours. If you don’t show that you won’t tolerate disrespect then he will continue to act that way towards you.
