My guy friend and his emotionally abusive ex (both 19) just got back together and idk what to do

My friend, who I've known for 8 years, broke up with his ex early last year after only a month together. They went to different colleges and a few weeks ago, my guy friend was asking if they should, I didn't want to tell him no since I thought it would make him unhappy but now I regret not saying it. His ex was my friend during freshman (or sophomore, I forgot) of high school (we were in the same class, talked and hung out together at school) after they got together last year, my friend started lying to me about stuff, avoiding me when we had already made plans, ditching at the last minute, etc I later found out that she was a really jealous, overprotective person, like maybe it was because she's clingy or she thinks what's hers is hers and she doesn't want other people to get near him (especially girls) I started hating her for "ruining our (me and the guy's) friendship." After they broke up, he went back to normal. A few weeks ago, he told me that he thinks she likes him again and was wondering if they should get back together, I didn't say anything since I knew if I told him yes, my life would be "ruined" and if I told him no, he would get mad at me, now I'm really regretting I didn't tell him no since he had ditched me when we were supposed to hang out the day before he went on vacation for a month since he said he was too busy packing to do anything else, and the day he was supposed to leave, he posted pics of them on a date with his (supposedly) gf before his flight...like did he lie to me again? I don't want our friendship to end up like how it was last year, I don't think I can trust him anymore...and if it didn't work out when they went to the same school, would it really work when they are in school like 100 miles away from each other?
