I'm delena fan, but I like Rose, I think that she and Damon can be good friends, and she care about him. Actually, she's probably the only one who care about him now that all worry about Elena and none exept Rose see how lonely Damon is. She reminds him that he has humanity and that he's not a monster. I don't think that Elena belive that he's a monster but she doesn't 显示 him that, that's why he think that he doesn't deserve her. That's my opinion and sorry for grammar 或者 spelling mistakes :)
Me personally? I like Rose and Damon together. i think she reminds if him, of his good, sweet site. Besides, I 爱情 when he's happy and I like when he smiles with her. I hope she's not going to die...
A producer of the 显示 说 in an interview that they aren't meant to be together and she is just a person who helps him to find his real personality and to 显示 him that he isn't that bad. And I still think he's totally in 爱情 with elena :)
