long story short, she be the girl who he let get away. a lifetime ago, when he was young and bright eyed, he might've even loved her, but walked away after he'd been tapped for a top secret black ops unit, in part to keep it secret, and also to keep her safe. we could hash out details on the how of it, if it was amicable, or if he was intentionally an ass to keep her away, blah blah. after the war, he just... sort of stopped existing, but came to terminus under an assumed identity about a year ago to check in on an old friend, so there's potential for a lot of different stuff there!
