My [24F] former fwb [25M] used to bully my boyfriend [24M] of 2 years in college. Should I tell my boyfriend I used to sleep with his bully?

I'm going to try and very briefly tell you a true tale from my life. I new a guy who was married for almost 20 years to his g/f from high school. The started dating as juniors and went all the way through college together and got married. Life was swell, typical 2 kids, literally a picket fence and a good home. That is until one day at a BBQ one of her fuck buddies from college showed up. Now remember when I said they went through college together? Well she apparently thought that being together meant she could also bang one of her friends to and I quote "get through the long stretches where they didn't see each other". Not once did the guy know about this, he had been living under the illusion that they were each others only other one ever. Of course the guy had no idea that the husband didn't know, so in conversation with another one of their friends he brought up a memory about being at a location at a certain time and when asked why they were there at that time of day the guy simply said "what do you think we were doing". The husband lost his shit right there on the spot. I've never seen such a melt down. At first he started going after the guy but people stepped in and then he started asking his wife if it was true and all she could do was cry. He knew then it was true.

I tried, we all tried, to tell him it was so long ago in the past and that they had built a family and a life together. But it was to no avail. He left the house and within one week filed for divorce refusing to talk with her. She was beyond destroyed.

That was almost 5 years ago. We live in a no fault no alimony state so they sold their home (for one hell of a loss because the market at the time was crap). They got joint custody and she lives in a small subsidized apartment and to the best of my knowledge is still single. He re-married about a year ago. I am not a fan of his new wife but hey its not my life.

Why did I tell you all of that? To tell you this. It always comes out. Somehow someway for some reason it will come out and you have to be ready for when it does. Your b/f may not act like the dumbass that my friend did (yes I think it was dumb to nuke his life like that, I mean I get being angry and hurt but to break up a family like that was just rough to watch).

tl:dr: At some point in time despite our best efforts the truth tends to come out. It may be a day a month or years down the road but it will rise its ugly head. Better to be honest now than to lose a life later.
