Hi, this is an opinion about a multishipper, I dont hate damon, stefan or elena , all of them has their pros and cons, this is how I see their relationship now elena as a vampire.
Stefan and Elena: We saw since this three seasons a relatioship based on respect, trust and above all LOVE, a kind of love different from others but still love, since season one stefan was supportive, caring with elena, although in season three this changed, at the end we see the real stefan, the one who respect elena choices's , he trust in her and he doesnt treat her like a doll, he knows she is a real person who can make her own decisions, she doesnt need a father, she needs a man who always support her, who know her mistakes and still help her and support her. Elena through all season three keep faith in Stefan, she always fight for Stefan and when she needed to back up, she did, she respect the choice of Stefan and even with all that happen, she never forget about him . "I love him" she said to Damon " despite of what I feel for you, I never forget stefan" despite Damon was her, she never forget Stefan she loves him with his faults and mistakes, that is love, she forgive him despite all.
That kind of love is real love, it doesnt matter the distance, you face the things together, you never give up, you always fight for what you love, that is stelena relationship until now.
Damon and Elena: Damon the caring and supportive friend of Elena, he is in love with Elena since season one, and although he made mistakes, he always do evertyhing for elena, the only problem, is elena doesnt feel the same, season one elena feels only friendship, season two lust and season three she develope some feelings for him because stefan wasnt here, but still she cant shake stefan of her, Damon consume her ,yes but consume her in a bad way, consume her like a flame but like a flame it is something that could be dangerous and could burn you. But still damon never is far away for elena, he doesnt let her think, he doesnt let her live his life, because Damon's love is like an obsession ( sadly for me) elena said to him: That is the problem.
Damon wants that elena doesnt think, he doesnt trust in her enough to let her make her own decisions, maybe that is the reason why elena cannot trust in Damon, delena relationship will be damon over elena all the time, like a doll. Elena as human cannot totally love Damon, as human she thinks, she rationalize things.
Now as a vampire, the lust will get her but not love, lust. As a Vampire you are dead, your feelings are not the same, sadly I will love to see Elena and Damon relationship as human but not as a vampire because everything change, although is the same elena, will be more like katherine, and the desire of damon will make her fall but not for love only because the blood, the kill will bring her to another state, elena doesnt want to be a vampire neither stefan or damon so now elena as vampire will change everything for her.
This is how I feel about this, I like elena, I like damon and I love Stefan ( yes I love stefan not because he is hot, I love his character just that) I know delena will happen and when they kiss at the motel, it was an awesome kiss who deny that but more touching for me was when she tries to get back stefan, her suffering, her loging for him was overwholming. So I know as a vampire she probably will get more close to Damon because he is all of fun and everything but at the end as human she always love Stefan first and I like Damon enough to make me feel sad for him because he will never get the love of the human elena, the women he loves first.
