Do NOT do this too much, though. I did this in my last relationship and it turned into resentment from me, while she walked all over me, knowing I would say sorry for everything. It wasn’t her fault, I should’ve protected my values more, but this is a slippery slope. However, my next partner in my opinion should take this and say something like “no, this is not your fault. Let’s work on it”.
It could go both ways. I can never change though; saying sorry is too simple for me
