did i totally mess up by hitting my cousin-in-law after his awful joke about my girlfriend?

So, I’m in a pretty rough spot right now. My girlfriend passed away a few months ago, and it’s been really hard. At a family get-together, my cousin-in-law decided to make a really cruel joke about her death. I lost it and punched him. Now my whole family is upset with me and saying I went too far. I know violence isn’t the answer, but I just couldn’t take someone making fun of her like that. I’m torn between apologizing to keep the peace or standing up for myself and her memory. I don’t want to make things worse, but I also feel like I shouldn’t have to let that slide. Has anyone else been in a situation like this? Should I swallow my pride and say sorry, or is it better to stand my ground? #familydrama #grief #needadvice #boundaries #RomanticRelationships
