Anyone know this song?;

For some reason a song popped up on my head saying "I didn't get to tell her how i loved her how much i cared" then my mind skips parts (x.x);; then it goes something something something "going to regret it for the rest of your life"

...Anyone know the song i'm describing
I think the genre is R&B or soul, but i'm pretty sure i'm wrong on that

And i think the first and second sentances don't really go in the same song...

Sorry if i'm describing horrably, my brain is just being mean to me >_<

Nevermind, i found the song ^^;;
But it doesn't have the "Going to regret it for the rest of your life" part, so i'm still looking >_<
