New watcher here & I'm disappointed

Spoiler ahead Just in case.. So I'm watching the show for the first time, fully. I had only seen bits and pieces before since my mom loves the show but didn't retain details. I already knew certain spoilers, but not all, and obviously don't understand them all or know when they come up. I just watched episode 7 from season 4 and I'm boiling in frustration.. I cannot, cannot believe that Elena just dumps Stefan for Damon.. After 3 seasons of "I love you, Stefan", "I'll never give up on you, Stefan", "I came back for you, Stefan", "I picked you, Stefan", "It will always be Stefan".. Damon has been the cause of so many problems.. and even though he's had small progress in his character development.. I am so not okay with this.. I will keep watching. I know there is more to come. On the other hand... I'm starting to love Klaus and his little thing for Caroline. I don't like her with Tyler, not one bit.
