My ex-boyfriend ( and u0026 first true love) is about to get married, but his fiancee is cheating on him. I'm tempted to send him a message and let him know. Would that make me an a**hole?Looking back, maybe I should've posted my question on the internet first instead of acting on it.Maybe if I'd just minded my business and let him go as I did before, then I could've focused on my own grief and the sad state of my life.Then again, maybe he shouldn't have responded...
