¿Crees que no siento mal de lo que hice?
Is this right for "Don't you think I feel bad about what I did?"
"¿Crees que no me siento mal por lo que hice?" or "¿No crees que me siento mal por lo que hice?"
You think that I don't feel bad about what I did? (The no was before siento so I changed the order a bit).
You know, I would have used POR also, but I think I've heard DE as well. Are they both OK? Gracias.
