The song is about someone whose heart was broken (cheating?), but found another interest.
The first "turning around" was the singer, either bashful of advances, or trying not to be involved until she's healed from the previous relationship, hence why everything is complicated the first time.
The second verse speaks of a mature relationship, that she and her lover are becoming so close that they can finish each other's sentences, seemingly reading each other's minds, and no matter how far they are, physically, they are still feeling so close.
The third verse speaks of another heartbreak (cheating?), leading the singer right back to the beginning, though she's feeling stuck, unable to leave him.
