Debbie Green. Remember? He asked her to marry him and then left her at the alter. She appeared during the Millar/Hitch run - one of my least favorite runs, IMO.
And that was one of the dumbest storylines. At the end, Ben had this Lois Lane moment, where he realizes that anyone he marries would be at risk due to his status as a super-hero. I've always maintained that Ben really missed a good opportunity with Thundra, though I doubt that union would have lasted. Or maybe it would have? They never explored it.
One day I should go back and re-read the Millar / Hitch run to remember all it's "fine points". Yeah, Debbie was a teacher and they had a whirlwind romance.
