Stay true to yourself. Only you have to live in your skin. You have the power to either allow good or bad things into your life. Be honest with your friend about the conflict your feeling within yourself. Keep the focus on you, to avoid the blame game. See what they have to say about it. Make the effort, but the outcome is what it is. Like you, only they have the power to make a change in their life. You can encourage but you can't decide for them. Nor, can you fix them. That requires action in their part. Besides, I'm guess your too busy being human yourself! You're likely have your own struggles and personal lesson to learn. HA! Maybe this is one of them. ;) Good luck.
