Out of the blue YS has reappeared. Not to me or W directly but to another relative who was intimately involved in his recovery from attempted suicide and against whom he has professed sheer hatred since he left the hospital. He has agreed to see us soon for the Easter holiday. Both W and I are wary and on edge. This is totally unlike his behavior for the past year. He has declaimed and delineated over and over again, in very strong language, his hatred for us and his desire to never see us again. And just last week, he exchanged texts with yet another relative which led to said relative stating that YS could not be trusted around any of us because of his anger and volatile mental state. The suddenness of this shift is really concerning to me. The relative mentioned in the first paragraph saw YS last weekend. YS asked for, and received, money from this wealthy relative. Cash money. I am terrified he will be using this money to purchase a weapon and harm or kill my W and others on the holiday. Possibly including me. It would be consistent with his words and actions over the past year and if he has grown totally unhinged....I can't bear to even consider the horrible possibilities of what he might do. I have no proof. He has made no threats that I am aware of. The content of the texts/calls he exchanged with our other relative were never disclosed. But that relative was adamant that YS not be allowed around the family under any circumstances due to YS' anger and overall frame of mind. I have no idea what to do. I am considering not attending the holiday dinner where YS is now apparently expected. I can't tell W what to do, though obviously I would prefer she not attend either. What would you guys do if this was you?
