So, I have this friend, let's just call her Stephanie who has a boyfriend named Raoul (yes, the names are fake). Through a weird turn of events I end up dating Raoul's sister, Eve.

Raoul has a serious gambling addiction. No joke with the word addiction, guy lost 200$ on a single soccer ticket. He can fuel his addiction because of his parents who are a rather wealthy bunch. Stephanie has had many arguments with Raoul about this problem of his but they worked it out everytime. Raoul apologized and promised he would never do it again, and Stephanie believed him for some reason.

One day, dude loses all of his money at slots or whatever and his sister has to loan him some money. Eve does exactly so and lends him some money and after some more fighting with Raoul everything seems fine. However, Eve tells me a few days later that he actually went and gambled all of the money he got from her as well and she had to lend him more BUT THEY NEVER TOLD STEPHANIE. They didn't tell her because they were both sure at this point that she was gonna' break up with him for this one, it was already too much.

Obviously I wanted to tell Stephanie the moment i found out but I was held back by two things, one, it really wasnt my place to invade their relationship and two, Eve would've probably broken up with me as well if i would've told her.

Fast forward two months after this, I've been broken up with Eve for a while now out of a completely different reason, and I remember this thing. I go and tell Stephanie everything about what happened.

TL;DR I ratted out this dude my friend was dating that was keeping the fact that he gambled again hidden right after having an argument about his gambling addiction with her.

My questions are ... Was I an asshole for getting involved? Was I an asshole for keeping this hidden from Stephanie because Eve would've broken up with me if i told her? Should I have kept my mouth shut or should I have told her sooner? Just any kind of opinions and judgement would be much appreciated, I'm really curious about other people's opinions considering how I've already done it and there's no changing what I did anymore.
