My boyfriend and I don't write each other songs but boy do we have sing offs with each other to see who does it "better". It's all in good fun :)

Either way, just sing it. If he cares about you enough he won't mind, if he's rude then deal with that accordingly. If it'll make you feel good, do it!

answer his question by saying "indeed, we are." and then sing your song like a boss.

Sit his ass down, tell him that damn right we are, and blow his mind with your heartfelt, disgustingly romantic song.

Well you could maybe turn the song into a poem...it seems like to me that's the only way out

Aw I actually feel bad for you OP. That sucks. Make him feel bad. You can get a foot massage out of it.

Did he know you were writing that song? 3 months is a long time to be writing one song so i'm assuming it's your first attempt. Eitherway, bad timing on his behalf xD. Sing it anyway, and own it like a boss.

Haha.. Surprise him or may be he found ur secret song already ;)

Well then you know your next request at karaoke night: Sara Bareilles' Love Song.

Well I hope you just sung it to him anyway, I'm sure he would of really appreciated something like that, no matter what he said.
