Why does everyone like Delena?

You have to read the books to fully understand, there's so much madami there than in the show. The books are so different than the show. For instance in the books Damon doesn't just kill people for the heck of it, he only does for self defense. Stefan's madami annoying and Elena's a stronger madami independent character, she can walk all over Stefan. Damon and Elena's personalitys are madami suited to each other. For me the best and most interesting parts of the books involve Damon and Elena. I really suggest you read them, it's an amazing series. I think the ipakita is really good but the books are awesome! And again the books are completely different from the show, you wouldn't be ruining any surprises. Nothing from the books has happened so far.

her and stan just rushed into it she needs to be with damon hes just ...beter for her

I agree that the books (although I have to admit that I have not finished pagbaba them all lol) really outline why Damon/Elena belong together but I have to say that the ipakita is doing a fine job of illustrating the exact same thing to me. Damon and Elena have everything that a couple should have, in my opinion; Chemistry, raw angst, passionate moments (including the fights), a believable and gradual unfolding of trust and feelings on both sides and most importantly they are getting to know each other before anything romantic officially happens. It's as if they are slowly building this solid foundation for friendship that will develop into the truest form of pag-ibig when the time is right.
I adore that they see each other for the real people they each are on the inside. No pretending, no lies (well, not intentional ones), and neither trying to be something they are not. Because they don't HAVE to be something they are not when they are together. Elena sees the Damon that he doesn't ALLOW anyone else to see and it's only with her that he really wants to try (with anything) in life again. She is what has made him change - and want to change - and for someone like Damon, who cannot easily open himself up to anyone, that is a monumental.
From Elena's POV, I find that she is somewhat hiding from herself (and after having gone through the traumatic experience of having her parents die, it's definitely understandable) while she lets Stefan be her safety zone. But as the ipakita is progressing and Damon and Elena's relationship intensifies/expands, we are seeing Elena slowly finding her way back to her real self through him. To me, Damon represents everything Elena IS but has buried deep inside out of fear of being hurt again. Don't get me wrong, I do think she loves Stefan (and a part of her probably always will) and I would also say that Stefan is something she likely needs in her life at the present time as she finds her legs again, but all the while she is with Stefan, it is Damon who allows Elena to be true to herself once madami and can meet her on equal ground.

Sorry for the long-winded response, I just pag-ibig the way this couple is blooming into epicness. They really are the puso of TVD for me.

Simple. Cz everyone believes that Elena's pag-ibig will transform Damon. Who just happens to be ruthless and obsessive.

Cause Damon is hotter~! lol
