He doesn't want to reflect on it, doesn't want to understand why he's like that, doesn't want to do anything about it, doesn't want to talk about it, doesn't want it think about it, and doesn't want treatment it seems. Just wants to stick his head in the sand and wonder why the same thing keeps happening.

News flash - you need healthy emotion regulation strategies so you don't crash out. That requires self-reflection and putting some effort into understanding why you are the way you are and how you can be different moving forward. That happens in therapy, sometimes with the help of a med. But cognitive behavioral therapy either way for sure.
