25, though your response was to alamo, it also helps me as I was wondering many of the same things. My original thought was to 'list out' the ways I hurt the relationship, apologize for each of them separately, and give to W for her bday or anniversary of our S. I'm glad I held off, as I think it would dredge up too many things. When W mentions specific things I've done wrong, I've been (I think) very good at apologizing, if not also validating.
I think my motivation for all of this is that W is the type that holds onto her pain and never lets it go. She has mentioned things I've done wrong years ago, which I've apologized for again and again. I have to keep reminding myself that I can't 'fix' her, so if she continues to hold pain and grudges and can't learn to forgive it's her issue and not necessarily mine.
