Misheard Lyrics My Fave Boyz II Men Song [Video]

Ok I was today years old when I learned that I've been singing the lyrics wrong to one of my very favorite legendary Boyz II Men songs. Has this ever happened to you? Legit this song came out over 20 years ago and for whatever reason this morning I decided to look up the lyrics, WRONG!

Let me tell you the part I got wrong...I've always sang the lyrics, 'don't want to believe I left her mental.' I mean, it fits right? The actual lyrics to the song, I looked it up this morning, are 'no, I don't believe our love's terminal.' WHAAATT? I like mine better. lol Watch the video, listen to the words and sing it my way then sing it the real way. Which one is a better fit? Which lyrics to which song have you been getting wrong all along?
