I think my Boyfriend cheated while on holiday.

Ok, I've never shared stories or sought advice but I'm hoping you guys could give me some clarity, or a new perspective if you will. My BF went on holiday this week to visit his cousin. I believed everything was ok until last night when I received a barrage of texts from my BF phone. It was a girl he met in a pub who said she was in his room with two other girls who really "liked him" and "wanted to touch him" because his face and body was so sexy".

I told the girl he had someone at home and basically told her to jog on but she kept texting saying how gorgeous he was and how all 3 girls wanted to f*** him.

My issue you know is what do I do. I don't know what happened however I do question just how they knew how sexy his body was and why/how he got into a position where he had 3 girls in his room. He's called but I've ignored it because I don't know what to say or think. What should I do?
