You know him better than any of us, so would he want it back? If it were me, I'd want you to keep it. If it was me, and you were his highschool sweetheart, it would break his heart if you gave it back. Especially, if this isn't too personal, but if you were his first. That would be like saying "yeah, guess what it really is over" and it would be coming out of the blue. Keep for your daughter, she'll love it
