Should I cut off my brother?

I’m sorry for the long post, but healthy and mature advice would be much appreciated...

My brother literally ruined Thanksgiving and Christmas with his HORRIBLE temper, complete lack of respect or hint of appreciation. Everyone got a taste of his venom and we have all pretty much agreed we cannot reach out or continue to help him in any way.

I suspect he has Borderline Personality Disorder. He’s admitted to extreme anxiety, drinking tons of coffee/alcohol, rapid mood fluctuations, history of cutting, and has torched through his romantic relationships and now my dad/my husband/sister/me. My mom is tolerating him for now.

Once he got home today (we live in different states) he blew up my phone with hateful texts.

However, after only a few hours he sent me a long and beautiful apology for his behavior and acknowledging he has a temper problem. He admits he doesn’t have the pride or energy to cut off everyone. He wants to call me tomorrow if I am ready to discuss and here is where I am torn.

What do I do? I feel he is finally vulnerable enough to accept constructive criticism and I want to encourage him to seek counseling. I don’t want him to suffer anymore. But I’m so overwhelmed and angry. Do I give myself time? I’m afraid if I wait too long our relationship won’t recover and he may never heal but I am so hurt. I’m in limbo.

If you read all of that, thank you 🙏🏼 I appreciate your comments ❤️
