I've been talking to someone for a few days now, I've had a friend talk to me about him for a long time, and as far as i can tell he's not mentally stable, has depersonalisation disorder and severe depression. He's a sweet person, but I'm not attracted to him anything more than a friend. He's been flirting with me a lot, opening a lot of doors and almost confessing to me a few times, I can tell. And I'm so scared that he'll ask because I'm scared that he'll do something he'll regret, and that I'll regret for the rest of my life. I know it'll happen, ever since my friend told me about him I knew not to get in touch with him, just to nod along to what she says about him and how nice he is. What makes it even worse is that it's long distance, I'll never forgive myself if something happens to hin, and I can't just lie and say I love him. I can't lie to him about something he's so passionate about, but I know that he's so close to the edge of suicide, and if not, if I reject him I'll lose all contact with his friends. So many of my closest friends, just gone, hating me for telling the truth. I don't know what to do, maybe this is all just in my head. I know what it's like to lose someone to suicide, I know the signs that lead up to it, and I know that my words aren't strong enough to stop it. Please, I need to know what to do. Do I lie to him and live a relationship built on lies or tell him we need to stay friends and risk losing him alltogether? I don't know why I care so much, I've never met him in real life, everything has just been phone calls and text messages, but I don't want to lose him and live in guilt for the rest of my life. I'm sorry if this is a bit of a tangent, this has been stuck on my mind all day and I can't focus or even breath without wheezing. Please respond any advice, any other options there are.
