This is something that has happened to many of us, i'm so sure of it. When we like someone's that's "TAKEN" by somebody else. I believe that there's always a possibility, I mean, if you like someone who's in a relationship and they're NOT MARRIED YET, GO FOR IT BITCH! He's/She's still essentially single so why not?.. You never know!
I don't support infidelity but I support braveness because sometimes we have to risk ourselves to achieve almost impossible things. DO YOU DARE?
