Suicidal boyfriend. Just need your support.

[c.jude]

My boyfriend of 8 months is having suicidal thoughts. He has tourettes, OCD, ADD, and corporlalia. I have been very supportive of him. He has with me with my severe allergies. He started his junior year in college this semester and is stressing and burning out. I also started working full time and we have not been able to catch up but once a week if that. He has been acting so weird lately. When I asked why, he told me to read his blogs and his chat session with his long time friend online. I did and he has been stressed due to us not catching up lately and school. He also has been so stressed, he has thoughts of taking his life. He wanted to smash his car into oncoming traffic but didn't since he didn't want to hurt another person or cause his family or I sadness. We talked about it after I read them and he told me I'm the only person keeping him sane. I'm the reason why he gets up in the morning. He needs me. When he's with me, everything goes away. I responded with this:

"So I read your chat and blog. Thank you for including me. I suggest you take a step back and look at your life. If you're burning out in college and skipping classes, it's probably something you don't want to do in life. Your suicidal thoughts are very serious and should not be taken lightly. You really need help. Please talk to your parents and phycologist and get it taken care of. I'm glad you can come to me when you need someone to talk to. I'm glad you feel better with me, but I am not the solution to your stress and problems. I can help support you, but I can't solve them for you. That is something you have to do. Please, please get it addressed and taken care of for your own good."

He still won't tell his parents. He is still living at home for college. His parents are supposedly very supportive of him. I'm just....I dunno. Needed to vent

Any thoughts would be appreciated. I don't know how long I can't take it. I need someone stable for a partner but I really care for this guy. I think if he doesn't get help I need to move on? I just...am confused. What at your thoughts? BTW, I am almost 18. He just turned 21. Thank you.
