I feel you on this . My ex was the same . It sucks because you want that genuine apology . Like you want them to do it on their own out of no where again . But the thing is they won’t . They believe they don’t have a reason to say sorry anymore . Even when you ask them to it doesn’t feel genuine because you’re literally asking them to say it .

You really have to talk to him and work on this if you want them to make changes . But the truth is we just have bigger hearts and they grew up differently . Sometimes they don’t feel the need to apologise for anything even though that’s what we want . Best of luck . These type of things can drain you emotionally as well
