Marriage?

My boyfriend and I have been together a year and a half (just started college). He got very depressed, spent a week in a mental health hospital, and dropped out of school. He’s been saying all along that I’m the only reason he’s alive, and I ended up agreeing to marry him at the end of the school year.

He seems like the kind of person I want to spend the rest of my life with, but I always planned on getting married after I graduated. Now though it seems like it would be best for him if he knew we’d be together for life.

Thoughts?
