Take to long to apologize

Does your s/o ever take to long to say sorry. I hate when i get mad and he acts like he doesnt know what he did wrong, i try to give him the silent treatment but hell go days i hate the fact hell stay next to me and cuddle like he did nothing wrong, then i finally give in and tell him what he did wrong and that he needs to apologize and it turns into a big argument he tells me he was going to apologixe he was just thinking of a way 😒
