Yea often times your friends resent you for interfering even if they asked for help. It's the whole "kill the messenger" scenario at play too. Sometimes you have to take a step back and let your friends grow up and handle their own problems. You're a good and decent friend for wanting to step in and help, but like I said sometimes things can go from bad to worse even if you had the best of intentions. Good luck.

Maybe the way you try to fix things between them is ineffective and alienates them instead?
