Hey y'all, I have a friend with bpd whom I have known for a while and he is like a brother to me. We've been through a lot and I've helped him break up with abusive exes and tried to give him advice and comfort during breakdowns as best as I can.

 We've had our ups and downs, and he's split on me before, but he's never cut me off completely until now. I have no way of getting in contact with him and it's upsetting. 

He was being unusually kind and flattering me for a couple weeks, and then I woke up today to be completely blocked and I can't re-add him on anything. I have no idea what's caused this. Any time he's ever split on me he's communicated about it and we've talked it over or taken a little break. This is completely out of pocket and honestly shocked me a lot.

I have no idea what to do and we had future roommate and life plans together and now that's just all gone. Does anyone know what's caused this? Is there a chance he might unblock and explain? I'm lost.
