I do not plan to contact him or respond to his attempts to contact me. He is blocked on Facebook (as are his aliases and his close family members). I will block his number if needed. And I have friends who are willing to stay at my house while I'm there in case he tries anything.
Good you have friends - this can help a lot!

Its okay to avoid the contact with him. Its also hard to deal with eventual suicide. It may help: You can not save him.
Keep going and keep us posted.
