As more and more chapters come out, I'm starting to see why she ended up confessing to him and not the other guy. He's there for her during the hard times more often then the other guy and he provides safety to her, even though on the surface she's scared of his attitude, his actions to her are reassuring and they leave a deeper impression of care (the pills, being there for her while she is trying to heal, and giving her a reason so she does not take the blame herself).
