You didn't specify the relationship so I'll go with a certain type here: Please Forgive Me Bryan Adams It still feels like our first night together Feels like the first kiss It's getting better baby no one can better this Still holding on you're still the one First time our eyes met same feeling I get Only feels much stronger I wanna love you longer Do you still turn the fire on? So if you're feeling lonely, don't You're the only one I'll ever want I only want to make it go So if I love you a little more than I should ... Please forgive me, I know not what I do Please forgive me, I can't stop loving you Don't deny me, this pain I'm going through Please forgive me, if I need you like I do Please believe me (oh believe it), Every word I say is true Please forgive me, I can't stop loving you Still feels like our best times are together Feels like the first touch Still getting closer baby Can't get closer enough Still holding on You're still number one I remember the smell of your skin I remember everything I remember all the moves I remember you yeah I remember the nights, You know I still do The one thing I'm sure of Is the way we make love The one thing I depend on Is for us to stay strong With every word and every breath I'm praying That's why I'm saying OR EVANESCENCE LYRICS "Forgive Me" Can you forgive me again? I don't know what I said But I didn't mean to hurt you I heard the words come out I felt that I would die It hurt so much to hurt you Then you look at me You're not shouting anymore You're silently broken I'd give anything now to kill those words for you Each time I say something I regret I cry "I don't want to lose you." But somehow I know that you will never leave me, yeah. 'Cause you were made for me Somehow I'll make you see How happy you make me I can't live this life Without you by my side I need you to survive So stay with me You look in my eyes and I'm screaming inside that I'm sorry. And you forgive me again You're my one true friend And I never meant to hurt you

There is a very moving piece by composer Thomas Newman that has that exact title. It is from the soundtrack of the movie Pay It Forward. You can find a sample here http://www.cduniverse.com/search/xx/music/pid/1044784/a/Pay+It+Forward.htm (It's #26)

Here is a slow R&B tune "I'll Forgive You" -Bobby Valentino Lyrics : [Verse 1] I might as well admit it That I still miss you I know what I said but it's Kind of hard for me And it's hurting me This is bigger than pride And I wanna give it another try I'm still torn in two But love made me make this decision so [Chorus] I'll forgive you But you really hurt me My heart wants to try us again I know you're only human But you almost destroyed me Our love was worth it Still I need a little more time [Verse 2] I hope you learned a lesson Bout hurting the ones you really love Cause I was a soldier for you Would have done anything to prove it to you Maybe we can get on track Rekindle the love and bring it back Cause there's nobody else for me My heart just wants to say this to you [Chorus x2] I'll forgive you But you really hurt me My heart wants to try us again I know you're only human But you almost destroyed me Our love was worth it Still I need a little more time [Hook] I got to figure this out We need a new start No more deceitful lies If someone told me we would be apart I would say you're foolish Cause God brought you to me [Chorus x2] I'll forgive you But you really hurt me My heart wants to try us again I know you're only human But you almost destroyed me Our love was worth it Still I need a little more time

Let's stay together by AL Green. I can't state all the lyrics but the gist of the song is Staying together through adversity.
