Should I tell him?

my ex-boyfriend has been going out with this trick for the last 6 months,last week I discovered she's sleeping with her best guy friend,when he's not around(he's in the army),i want to tell him,but when he left he was quite upset...over something she did,with another guy,she told him she would change...and recently he texted to tell me..he thinks she's the one..and things are really good..they talk everyday...but I know its bullsh*t...should I tell him, i don't wanna come off as trying to kill his r.ship...we decided to remain friends,and we both deeply care for each other...i just don't know...
