This is a verse from Bruno Mars' song When I was your man:
Same bed but it feels just a little bit bigger now
Our song on the radio but it don't sound the same
When our friends talk about you, all it does is just tear me down
Cause my heart breaks a little when I hear your name
What does tear me down in line 3 mean? I've looked it up and oxforddictionaries.com defines it as:
US informal criticize or punish someone severely: they tear a man down and threaten him and then they give him another chance
but I have a feeling that it means something else, is this the correct meaning of the phrase in this context?
