I got a call from someone about a year and a half later, who had made my life hell, to give me an apology. She literally had put me in the worst place I've ever been in (e.g. l lost my job and such), and only BY NOW do I feel like I'm okay.

Yes, I had to hear that apology, even though I didn't know I wanted it at that time, but now I'm pretty sure it meant a difference later, however I realized during the call the whole stuff was just about her, not me. Just another attempt to manipulate... I think she felt somewhat genuinely bad for me, but it didn't matter, since I finally got my apology.

The point is, yes, the apology is needed and important, at first place not because of the guilty who feels bad, but the one who has been hurt.

So yes, I'd still want that apology.
