There are a lot of hate on Rose for her being mentioned so much after series 2 and I honestly do not understand why it annoys people. If あなた know the Doctor well and watched the first two series of new Who then あなた shouldn't be so annoyed.
Lets look at the facts. The Doctor met Rose right after the Time War, where he literally ロスト his ホーム and his people. Although he was a rebel he still was incredibly attached to his ホーム and he ロスト it. He did not have any anchor left so he was filled with anger and guilt. The first person who actually got under his 'shield' was Rose. He was sad, nothing left to lose and then truly began enjoying his adventures after he met Rose.
Before that he did not seem to mind the idea of dying as he 発言しました it to Rose the first time he met and saved her. When he worked with Rose it gave him a thrill that he didn't think would ever find again. He found that she made him better even in the first episode because he came back and asked her twice. Before her he had never asked anyone twice. He needed something and he saw that something in Rose. But his trust and faith in Rose was not fully formed yet. He did not want to suffer a loss so soon so he tested Rose to see whether she would leave him after a bad adventure によって taking her out to see the Earth's end on her first adventure. This way Rose gets the taste of the life with Doctor and if she wanted to leave she could leave then. That way he would be less attached to Rose. He also wanted Rose to feel how he feels and took her there. But when Rose decides to stay it warms him もっと見る because it was then he understood that she wouldn't just leave him.
After this both of them become closer and start trusting each other irrevocably. The Doctor even deems Rose 'the Best'. Also his attachment to Rose is shown even もっと見る when she is 'disintegrated' によって the Ann Droid in 'Bad Wolf'.
The Doctor's face becomes blank, obviously going in shock because of the loss. The shock soon turns into anger and he even steals a gun when he, Jack and Lynda get out of there. This is important because the Doctor hates gun yet he took it after her loss. He even sacrifices his life (literally) to save Rose. But even while dying he dies in peace because Rose, in a span of only a year, healed him enough to be better. Although he still has the guilt even as Ten the guilt is less compared to his Ninth incarnation. The Ninth Doctor was born in a war whereas the Tenth Doctor was born out of 愛 for Rose. So his attachment to Rose becomes two-fold in that incarnation.
They 表示する affection もっと見る openly and rarely fight like they did before his regeneration because they solved all their problems in his Ninth Incarnation. The trust and affection between the Tenth Doctor and Rose becomes もっと見る palpable with time. His trust on Rose is shown in 'The Satan Pit' where he explicitly says that he 'believes in her'. He is certain that she would save herself and his blind trust on her is shown. The Doctor knows Rose can take care of herself, she doesn't necessarily need her but he needs her. His affection and attachment to Rose is shown also when he violently he reacts in 'The Idiot's Lantern' after he sees what the Wire did to Rose. He becomes a loose canon and dark. It was the first time he acts もっと見る like his Ninth incarnation because before that he was もっと見る happy go lucky. He thrashed out because for the moment he ロスト the only thing anchoring him to humanity.
This is shown again in 'The Runaway Bride' because after losing Rose he becomes darker; he kills the Racnoss and also によって just stands there watching them die. Rose anchored him to humanity and he had learned to depend on her. She was there since he ロスト his ホーム and since his Tenth incarnation's birth. When she was snatched away from him so cruelly he ロスト himself momentarily.
In fact, in 'Turn Left' it is shown if Donna wasn't there to snap him out then he would have committed suicide right there.
This attachment is very hard to get over. After Gallifrey she became his anchor and with her ロスト as well, it wounded him. There is no way he would over night just forget her. Rose Tyler healed him, understood him and seemed to complement him. So obviously he would without a doubt, mention her in series 3.
