Why do men self-sabotage?

My boyfriend of 3 years, known for over 5 is like a detonating time bomb. He’s unable to stay at a job and now wants to move 15 hours away solo in the fall. It hurts me because I have been so patient with him and supportive, so the fact that he wants to leave without me is upsetting. He says that he does not know who he is without me and needs to find himself.

He’a gone back and forth all of these years about what he wants (marriage, kids, our future, etc). I should also mention that he is bipolar and not on his medication (hasn’t been for years now) and I feel like if he were taking the right medication, this would help him.

Obviously, I’m not going to force him to stay. We are our own people and he is an adult— he is free to do as he pleases. I just can’t help but think that if it weren’t for his self-sabotaging behaviors and tendencies, things would be better and he wouldn’t be trying to leave.

I’ve done quite a bit of research on self sabotaging behaviors and he checks off every single one. How do I discuss this with him to help?
