I’d say that eugman should never have gotten into the relationship in the first place. Usually—I mean practically always—when someone is as seriously unsuitable a partner as his ex-fiancee sounds like, the evidence of that can be seen rather quickly, before you become a couple or best pals or whatever.
But, as eugman pointed out, his experiences and temperament didn’t give him the best skills in this area, so it’s no more reasonable to expect him never to have dated her than it is to expect him to have gotten out sooner.
