She did love him. In her crazy ways, she's been more loyal to him than Rogue.
The question is, did he love her or was just hormones + puppy love + sense of familiarity? He willingly cheated on her only months before their wedding and I doubt it was the only time. When he bought that house, he never mentioned "to settle down with Bella Dona". If he bought it after he left, he was very much ready to move on from her.
