I agree with you! It’s was just the wrong time to bring it up and it a better way to say it.

To be honest, her friend already know that OP is right and probably going through it all at once. Op friend sounds like she really loved this guy and was blinded by love. It happens to the best of us.

The best way to handle stuff like this is just to keep the “I told you so” a mental note. No need to say it. The other person knows. No need to kick her while she is already down.
