DEAR LmE Readers: My Ex-Girlfriend Who Is About To Get Married Wants To Sleep With Me

My ex-girlfriend is about to get married and I am also dating someone else but she is still insisting we continue having s*x until after her wedding.

 

As I type this, she is seriously disturbing me. She was very nice but I just can’t do it because of my conscience. I put myself in the other man’s shoes.
Also, I am worried that after the wedding, she might still want to continue sleeping with me because she has been complaining that her husband-to-be does not as well as I did.
What do I do? I am confused.
