I wouldn't go. I'd maybe send a card saying you feel conflicted and feel you can't contribute to what happened by being there, but that you wish them well (if you still want a civil relationship).
Alternatively, if you did want to go you could speak to your other cousin to find out how they feel about it, like have they moved on? Would they feel betrayed if you did etc
