It just comes across to me as: Why is he so melodramatic and basing his happiness on whether or not an 18 year old high-school girl reciprocates his "love"? Who is she really? He's lived for how long, met how many people, experienced so many events, and this is who/what his life is meant for now? It just makes no sense to me.
Exactly. Damon supposedly "luuuuuuuuuving" Elena never made any sense, except providing the writers a semblance of "Triangle", which was never effective and became fast boring.
I could get that Damon loved Katherine: she was one of a kind back in the days, and matched his personnality once he turned. But Elena? At best she pitied him, but most of the time, she hates and disapproves everything he is, she is not fun, she constantly reminds him she loves his brother...
They completely screwed his character with his "luuuuve" for Elena and made him nothing more than her pet: he is allowed to bark/bite only when she tells him to, when it is in her favor, but gets slapped on the nose as soon as he deviates from "her" moral compass.
I wish the writers would finally admit the Damon and Elena is doomed and wouldn't work anyway, and allow both characters to evolve on their own.
