Please help a grl out ! Name this tune??

Ok, the start of the song goes..
"My heart implodes, my heart implodes.... oh oh

Some of the lyrics are

"I smile for a second then its gone,
When i realize that i am all alone"

The chorus- "I fall in love with you, oh i fall in love with you...."

sounds like peter, bjorn and john, but i tried searching and found no such song from them like this one. Please help!!
This is driving me bonkors!!

"Teen Love" by Peter Bjorn and John. You're mishearing the lyrics, which I can't find to post. You got the right band. Hope this helps you and welcome to the forum.


EDIT: Something along these lines:
