Sorry I missed your reply blackloss. Piling a guilt trip on you isn't fair, so don't think of his threats as your problem, however hard that sounds. In my experience, people who talk that way, or act that way, are not really considering suicide, just trying to scare others into doing something. I know it's a few days later, but I bet things aren't so scary now. At that age, I had friends who thought it was cool to talk about death and depression and all things black! They all grew out of it - so will he. Getting back with him as a result of this threat will make you MORE miserable than before. What kind of sad relationship would that one be? Better not leave in case he tops himself? You'd never grow to love him then, would you??? You should be running in the opposite direction and not looking back.
Hope graduation yesterday was fun. Today is the new start you need, so off you go and grab life by the b@lls. Steer clear of doom-mongers. If you feel like one yourself, concentrate on becoming something else! Be happy.
