I'm really sorry babe

I made a stupid mistake cos I was angry at you
and now I'm thinking of him and I know it's wrong to do.
I have never cheated on you and I didn't cheat with him,
But he said that I was beautiful and I was tempted to give in.
I restrained myself from his arms, but I let him into my heart....
and I know that I still love you but you nearly tore me apart.
I'm sorry that I have these feelings, I'm sorry that you two are friends....
But I had to let you know and I hope that us won't end.
I'm really sorry babe, I'll try not to feel this way....
But please know that I love you and that I'm sorry about yesterday...
