Broken Wedding Vows

I'd like to forgive you but there is no way that I can. We've only been married for three months and you're sleeping with another man. When you vowed to be faithful, you were not sincere. You couldn't even be a faithful wife for half a year. I found out about your lover and you don't even care that I know. Unlike you, I intended to be faithful, this is a devastating blow. When we met, you were pregnant with another man's baby but I didn't mind. It was stupid when I thought you'd be faithful, I can't believe I was so blind. You've hurt me beyond belief, you've cut me to the quick. You broke your wedding vows and you make me feel sick. When I learned that you were unfaithful, I wanted to believe it wasn't true. You're not being faithful to me so I have decided not to be faithful to you. (Even though this poem isn't about me, it's based on a true story)
