Trying to break away from someone who's mentally ill

[StayingStrong123]

I love someone very much who's mentally ill. He's my best friend and more, though it has never become a full relationship due to his illness. He's an incredible person in so many ways, super, super talented and intellectual, and very high functioning. You would never know he's ill. But I do because of the hours and hours we've talked. He has a list of things, seemingly ocd, maybe autism, bipolar and delusional disorder (I've gathered from reading, but I'm not a Dr.), that keep him from living a normal life. He believes he's chosen by God, for example. Has obsessions with numbers and dates. So many details I don't even want to say because it sounds laughable and he's entirely serious and I definitely don't find the situation funny. I'm the only one who knows he has these thoughts. It has just gotten way bigger than me, and I can't force him to see reason or get help, so I think it's time for me to break away for my own health. I just can't get myself to let go.

When you say he has 'a list of things' has he ever actually been diagnosed by a Doctor?

Many years ago at the onset, yes. I wasn't in his life then and I don't know the details of those visits. He was put on medication but he didn't stick with anything or follow through because he doesn't accept the diagnosis.
