Who does the song this R&B song?

It goes " I wanna be the one to love you, cause I will always love you so, and I wanna be the one to fill your life with sunshine" also later on in the song" we'll take a vow to love one another, make this dream a reality","can it be you and me until the end of time" These lyrics are a little out of order and spotty at best but I only have a vague memory of them. It is a slow song ,sung by a male group, and came out about 8-10 years ago. If anyone thinks this sounds familiar what is it cakked and who performs it please? Thank you
