I don't know if it's ever OK for someone to be selfish. Perhaps there's a time and place to be self-centered, but I think selfish never wins the race.
My heart gets very tender when it comes to playing someone who has wronged someone else. I almost feel like it's easier for me to play having been wronged than it is to actually feel like you had an active part in hurting someone.
My musical taste is like a 16-year-old girl's when it comes to working out - Rihanna, Black Eyed Peas, Miley Cyrus. I love it all!
I use only essential oils for perfumes.
I do think that with any kind of infidelity, on some level - unless you're dealing with a sociopath - there's always a reason.
Infidelity is horrible - there's nothing worse than that; it's devastating.
