I honestly don't think the Doctor really loved Rose. I seen it as the Florence Nightingale effect. The Doctor had just killed off his whole planet (Or so he thought) and his hearts needed healing. He found Rose who was all to willing to help him to heal. So a bond was formed between the patient and nurse. Yet upon her disappearance into another dimension he had time to think. Now I don't think some of those feelings were totally lost. Not in the least. However he did figure he didn't love her like that. So when she had the ability to travel with him again he wouldn't allow it instead leaving his Doctor/Donna made clone behind in his place who still needed her. He even admitted that he didn't need to be healed anymore but his meta Crisis Doctor clone did.
Now don't get me wrong I do love the characters and there actors but thats my take on those two being in 'love
