He needs someone with the patience of a saint. You're going to have to deal with a lot of things. Mood swings, teasing, and the fact that he's often harsh (even when he may not mean to be). He can be difficult. His partner must be able to accept all of this easily, without blowing up at every little thing.He's spent many years feeling abandoned and distancing himself from others. To have someone who is very openly loving toward him would be a welcome change, and would certainly help him settle.
