I recently found out that my fiancé cheated on me with a girl from his work. I found out and then he admitted everything to me. He has only kissed the girl and sent some very flirty text messages with lots of sexual nature. The girl has also been sending him naked pictures of herself. I have decided to give him another chance because I love him and he has apologized non stop since this happened and has completely stopped talking the girl. Also we have a six month old baby, so I don't want to throw this relationship in the garbage..
Anyway, I do not need advice in my relationship, I need it for the girl's. The girl that he cheated with has an 8 month old baby with her fiancé. They already have a wedding day set for two months from now. I do not know her fiancé but I feel like I should tell him what his fiancé has doing behind his back. It has been bothering me for a couple of weeks since I found out. I just need to know if I should shoot him an email about this or not. I know that I would want for someone to tell me if my fiancé was cheating on me 2 months before our wedding.
What should I do??
