Thank you.
I felt as if he was triggered in between whilst we were speaking. Perhaps it was something i said to him which got him really angry. As at the start of the conversation he was pleasant enough, he even said he appreciates me calling him. Because he asked how comes i called, as we hadnt spoken in a while and i told him just to check up on him and he said he appreciates it.
Then afterwards he got aggressive.
Im feeling ok. Still puzzled with his actions. But im not upset or anything.
