The first time the Doctor allowed himself to love a human as in return as she loved him was when he met Rose Tyler. Yes he'd known countless companions, many of them human, some of them not. Yes he'd loved them all as well some more than others but he'd never had returned their very fragile human love to them in the way they given it to him. The difference with Rose he'd knew was that he'd been more free to love her after he'd lost everything else he'd held dear. When he'd met her, he'd been broken in more ways than he could count and if he were completely honest he'd been ready to just give up on even living.
But then he'd met Rose, and with the simple act of grabbing her hand, telling her to run he'd lost himself to her. She'd had him from that moment on out even if had taken him awhile to realized what had happened. She had helped the broken old man that he was want to live again. That's why when he lost her he knew the innumerable tiny pieces his hearts had shattered into would never be put back together again and once again living had become a too great burden for him to bear.
