It is, and this is the first time Melanie's actually used the l-word in regards to her relationship with Kurt.

"I've never really been the best with relationships, either." She really, really hasn't.

"But I wouldn't trade the one I've got now for anything else." She means that. She's happy with Kurt, and she really does care for him. Sure, Melanie had never really thought that she’d end up dating a blue, fuzzy elf, but apparently life is full of surprises.
