How to communicate needing space?
Recently I've noticed this problem in my relationship that when it gets late or I'm tired or had a long day I get upset by little things my partner does. Which is unfair to him. I noticed that 90% of the time we have a conversation about what upset me I don't even remember it the next day. So I feel like it's better to take a second to realize why I'm upset and cool down rather than talk about it when it isn't an actual problem. Usually I'm just tired or stressed and not actually mad. To him it still looks like I am upset and he wants to know why. It's also very unlikely for me to want space. I feel like this is better than just communicating things that I don't really care about the next day but me pulling away to calm down even for a little bit seems to put him on edge. He wants to resolve the problem but there isn't a problem and I feel bad talking about things he didn't actually do wrong. What should i do?
