I'm thinking especially of his song in "Dance With Somebody."

This has been on my mind a lot, too! We know Kurt can reach out to Blaine like that, in terms Blaine understands. I think it took a lot for Kurt to put his love on display, even in the relative safety of Glee Club. I really would like something like this, Kurt being able to make such a gesture. I don't want to see Blaine having to grovel and punish himself more in order to get Kurt back; that wouldn't feel very functional to me. They'd just be setting them up for another failure. If Blaine feels that he does not have nor deserves Kurt's unconditional love, that he must constantly prove himself worthy, he won't heal either. (Ugh, I'm babbling.)
