I was with my ex for 2 years and a half. We broke up cause I was going away for some time to study and he didn't want to do long distance. While I was away studying he hooked up with my cousin, even though I did indicate that she was my cousin when we were together. They continued to just kiss he told me a time when we decided to do long distance while he went away to work elsewhere. On this island where the population is less than 5000 people...how can one not know? I've been back on island working, he left to work elsewhere and my cousin and I only began talking last year. Currently, he is back on island and been driving her around to do shopping....a little birdie told me. It errrkkks me that they are hanging out together knowing the hurt they caused me. How do I express to my cousin how I feel about them hanging out. Should I leave them and leave the past in the past?

Imagine your friend is still chilling with your ex...how does one approach this kind of situation?
