I think that is still his motivation, sacrificing his normal life is a byproduct which he is struggling with before she actually goes into hiding Like the scene when he's frustrated, drawing the suit throwing it in the fire or when he's at his parents grave attempting to plead with them. He can either move on or continue to live in the past giving up his normal life. In the end they both go down that path both ending up as solitary figures. Sure, it's because of a failed relationship. But thats more a final trigger for a motivation that already existed (for Bruce).
