Andrea,
I think that you being there and caring about him did make a difference. So what if you were not the one who called? Someone did, and he made it. If it happens again maybe you will be able to call someone for help. But when it comes down to it, you are a caring friend, and that is what matters. You can not take responsibility upon yourself for his choices. You are not his doctor or his therapist, and even they can't take the responsibility if he chooses not to take his meds and makes suicide attempts. None of us can control what another person does. All we can do is be a friend, tell them we care and hope they make the right choice, and set a good example. Beyond that, you have a life of your own and you need to live it. Please don't let his choices stop you from following your path and enjoying life. Don't let him make you feel guilty. You are a good friend.
