I need help /b/. I met someone about a year ago and we got on pretty well. They was going through some issues and were suicidal and depressed. I helped them through it and started a relationship with them. Its been two years now and I've gotten to the stage where I don't want to be in the relationship any more. They regularly tell me how much they love me and that they don't know what they'd do without me. I'm worried they'd slip back into depression or kill themselves if I left. I feel like I'm stuck. what should I do /b/?
