I love my best friend

"It's Because You Love Me" is such a poem.. but its in ab ab ab ab format. :( sorry

I also have "When Friends Become Lovers" it's in abab format. But I'm not sure if that's what you are looking for.
Anyway.. good luck.

i have a poem called "they'll never know" and another called "my internet friend" both are in abcb format

I have one called "You Are My Best Friend". I don't know if that is what you are looking for but there it is.
