By the way, I think I'm in love with you
And um ... BTWITIILWY?
|BTWITILY||By the way, I think I love you|
|BTWITIAILWU||By the way, I think I am in love with you|
|BTWITIAILWY||By the way, I think I am in love with you|
|143444||I love you very very much|
|ILU||I love you|
|iluvu||I love you|
|ILYLC||I love you like crazy|
BTWITIILWY stands for "by the way, I think I'm in love with you." Obtuse romantics might use this acronym to reveal their feelings to their bf or gf.
If you think you have fallen in love with your SO, it is likely better to tell them in-person (or at least via an actual coherent sentence) rather than by sending BTWITIILWY. Clear communication is one of the hallmarks of successful relationships, and BTWITIILWY is anything but clear.
