He hasn't been txting me. Last time I talked to him he wanted to kill himself. That's the last I heard. Nobody has said or done anything. I really deserve to know

May I ask how old you both are and how long he has not been texting you?

Who is 'nobody'?

Does he live alone? Can you call his family?

How long is a long time, he has not texted ? And how else do you see each other, when do you date, see each other in person?

If you have not heard from him in 4 hours, or 4 days ?

If he is a boyfriend, you drive or take a bus to his house and check ?
You call him on the phone ?
You call his family and ask about him?
You call the police, and ask them to do a welfare check on him?

You aren't telling us anything useful. Why haven't you been to his house or apartment to check?

Is this an online boyfriend?
