Depends on what it is that u need him to appologise for ..
Sometimes if it’s just a misunderstanding then , moving on and him being nice to me to compensate is enough ..
I might ask something like “ I feel very hurt by ur word such and such, did u mean it this way??” That way he gets to explain that he ddt mean it and it’s almost always leads to a sorry.
However if it was something that completely crossed the line , like swore at me and so on, without me crossing the line first ... like if I haven’t crossed the line first and he was the one to do so.. I would expect and apology... I would be emotionless and not speak to him until he does ...
However... really in a marriage... there are times when both parties need to take some responsibility so not always the man not taking responsibility means he doesn’t value u.. it could be that he wants u to also take some part of the responsibility ...
Sometimes I just think about whether I had contributed to the misunderstanding and acknowledge that... appologise for my specific action but tell him that it doesn’t justify his action and overreaction what not... and that he could’ve expressed himself less hurtfully and give him examples ..
Some people have been raised in environments where a lot of blame was directed at them in an overwhelming way that they’re scare dto take blame so sometimes guiding the process helps.
But u know ur partner most.. usually after a soft speech when ur both calm it should lead to an apology from both of you to each other if things went out of order .. or from him if he unprovokedly wronged u..
If he never apologizes, I would personally- and I realize this is controversial, I would have a serious word with him about fundamentals of relationships and perhaps dig deep and get some sort of intervention .
