Could be wrong, but I think she's talking about how she loves this guy, but then they go long-distance, and when they finally get the chance to meet up again, he's not who he was before.

First verse seems to talk about him going away, second talks about them talking on the phone or something and her sensing change, then obviously the little bit about her noticing it. Then the third verse seems to talk about them finally being with each other again, hug, but she knows he's not who he was before; thus the misplaced love.
