Incognito gave you this excellent advice back in August. It still applies today.

You are allowing him to involve you in his mess of a life and are also now part of the reason he is depressed. Step back and let his family and the professionals handle this. If he is better in the future maybe you can be friends again, but you also have to ask yourself how being in contact with him will affect his depression since he has feelings for you while you have none for him.
Your compassion is a bit misguided here and you involvement is actually a hindrance to his recovery since he has feelings for you. I'm sure that isn't what you wanted to hear but it is what it is.
His state of mind isn’t your responsibility and you need not feel guilty for what he decides to do with his life or his death. Don’t let him make you think that you are. Don't enable him by feeding his need for manipulation. Step away and stay away, if he should be sucessful in killing himself then that's his choice and it's not your fault. By staying in his life he still wants to kill himself anyway so don't let him rule your well being while he decides his own fate.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
