1000% agree.
I grew up, for a variety of reasons (scary parent, autism, bullied, etc) with the default setting that I am the one in the wrong. So sorry came easy (too easy) to me, and I would ask lots of clarifying questions and go back over my actions to see where I could have done things differently, as default.
I feared conflict, but this presented itself as me wanting to be able to understand what I did, say sorry, be the one in the wrong, and then the conflict can be over because I can fix it (its in my control)
I never wanted to be causing anyone any hassle, so if someone had a problem with me who I cared about, of course I jumped to fix it!
I was then very very surprised to find out that other people react very badly to being told they have upset their loved ones, and get defensive or just ignore/bat off the problem. This made no sense to me. How could you not be upset that you have upset someone, and not want to work out exactly what the problem is so you can fix it? It was only much later I realised that this is also conflict avoidance, in its own way.
I do think that we should make it less acceptable in society to continue a relationship with someone whose immediate response to conflict is defensiveness and/or stonewalling. First few times, okay, they are still learning, you cannot grow without opportunity to do so. But to continue a relationship with someone who does not have the ability to recognise that when they have hurt their partner and the partner raises it, their immediate reaction is to lash back out or ignore it... surely that person isnt emotionally ready for a long term relationship? Not everyone is perfect or has perfect skills, but surely 'if you have hurt your partner, try to go into it with kindness and resolution in mind' is a bare minimum. Doesnt mean you wont get defensive, or shout, or struggle, but the attitude of 'lets figure this out together' should be a baseline. Why is it we can recognise that a 15 year old doesnt generally have the emotional maturity to be a parent but we cant recognise that people without basic conflict resolution arent ready to be long term partners or parents?
Also, there's probably a gender element at play here, would love to read more on that if anyone knows of any resources.
