Betrayed in Morro, S.P.

I'm from Bahia and I've had the opportunity to enjoy the natural beauties of my land several times, but this experience that I'm going to report made this time very special.I'm 30 years old, I'm a doctor and I'm engaged for 1 year to a doctor as well.In total we have 3 years together and the fact here told happened in the New Year's Eve of 2002\\2003 in Morro de São Paulo. My fiancée is a blonde of 1.74m, very beautiful and with a pair of legs that really makes many people "babble".At the last reveillon we went with a group of friends to Morro and as we had great difficulty finding last-minute hostels ((we only managed to get rid of the staff at the last minute) we ended up staying in a house together with everyone.There were friends of hers who had rented this house and in total they had 8 women and 5 men.Let's get to the point:On the night of the 30th, I decided to take one of those.As I hardly drank anything, I immediately became super "tall".I remember a guy who came to talk to my fiancée all cheerful and full of intimacy.I asked who she was and she told me she was a friend of my cousin, but she hardly knew me.I was very convinced of this, but I didn't want to spoil it, so we left the house and didn't really know how to start the night.When I got there, I said I didn't want to spend the whole night. It happened that my fiancée, seeing me sleeping, went back to the beach and joined our group of friends. She had already taken them all and together this cousin decided to go for a walk on the beach. Then she gave me a hint about this guy, then I found out his name was Adriano. In fact, I only found out about all this because about 4 months after this reveillon she finally found out about a betrayal of mine and decided to throw me in the face what I had done. She told me (in a fit of rage) that she had already been in the role of Adriano about 5 years ago but at that time she hadn't rolled anything, there were kisses and handshakes. A few days later that night, my bad luck, I was excited to meet this guy because he started chatting with her and he agreed to go to the back of the bar today, especially if my friends weren't sleeping there. We got up in front of the house and started chatting for a few minutes, and she didn't know the truth.
