I'm not sure... I don't think there's anything wrong with needing space after an argument but I identify as codependent so I'm not sure I can really say. If the X and I had an argument I would just need about 15 minutes to cool off but he would tend to follow me around and not give me my space which just irritated me more and prolonged the fight. I told him too that I just needed some time to cool off because I did so very quickly. If you tell him that's what you need and why you're upset I don't see what's "wrong" with that. I did so as a safeguard against saying something I didn't mean in the heat of the moment. I didn't want to hurt him
