Before you all start telling me that would be cheating, i would like to explain myself. My boyfriend has told me that he didn’t want me going on his summer holiday with his friends because his ex will be there. As much as I wanted to go at the beginning I do not want to be in an area where I was initially unwelcome. During the time that he’s going to be away, I foresee myself being lonely and alone. Would I be an arsehole if I saw other people during this time? 

Tl;dr boyfriend is going on a holiday that he avoided me from. I’m going to be bored. Can I see other people during this time?
