Long running disagreement.
Partner often says I've got annoyed with him and wants me to apologise. This can happen when I raise an issue with him or if something has happened that has annoyed me or sometimes when I don't even feel annoyed internally but he has decided that I am showing him that I am.
I have tried to be careful with my words and tone. I don't think I am coming across as annoyed to the extent that it might make him uncomfortable. And a couple of times I wasn't even feeling cross at all.
I have tried explaining that I'm annoyed about this thing that happened between us/situation and not annoyed at him - or I'm not annoyed at all - but he tells me that I won't know how I come across to him.
He will bring it up in an argument that it's unacceptable for me to come across to him like that. That he wants it to stop. I think that sometimes I have a valid reason to be annoyed when trying to explain/discuss something that has annoyed me. Do I have to be more zen and show no signs of annoyance at all? Although I feel like I'm already being calm e.g. no shouting, swearing, name calling etc. And in some of the instances he brings up I wasn't even feeling annoyed at all so I don't know how he's decided that I am.
Should I just apologise anyway as it isn't a big deal and he does know better how I've come across to him?
Deep down I don't feel comfortable about this.
