Dilemma

Hi all. So I had a few suspicions of my best friends boyfriend who is also a good friend of mine, I took it upon myself to join a few sex apps and I found my best friends boyfriend, no picture but having seen these apps in the past knowing they belong to him, I knew it was him. As I’m seeing someone. I didn’t talk to anyone on these apps and soon deleted after. Do you think I should tell my best friend or leave it be? I’m in two minds. I feel guilty for not telling him, as he’s my best friend and his partner is also a good friend of mine I feel maybe I should say something, but I don’t want to potentially risk ruining any of my friendships with these two. Also, I don’t know what’s happening in their relationship behind the scenes, and why he would be on these apps whilst in a relationship. Could my best friend know and be ok with it, or is his boyfriend (my friend) be feeling neglected in any way, due to the lockdown he doesn’t wanna see my best friend although they’ve met once or twice a week for an hour or so and then he’s gone home, but I don’t get why he doesn’t wanna see his boyfriend but be happy to wanna meet others online. So it does make me wonder, just wouldn’t mind some genuine advice on this please, thanks all 😊👍

Hey, I know this will be a hard answer to take in, but it's surely my opinion. Your friends life, it's his life and not yours. If he is betraying your friend, it's still noone of your business. Believe me, I know you probably like your friends a lot, but your life is your life. If it was your boyfriend it was a different story. Leave it be. If one thing is certain is that they will find out this on their own. Don't mention anything about it. Don't ruin their relationship.
