<human>: One of those seriously intense relationships with all the drama and passion in the world... but very problematic and erosive to both of our lives and wellbeing. He broke up with me a week ago. This wasn't the first time we've broken up, but we always found our way back within hours/days. 

It was probably for the best, but I love him so much- I'm so attracted to him, his looks and persona alike. I did not allow myself to feel sad the first couple of days, thinking it would all be for nothing once we got together again, as is our MO. 

He means it this time. Its over. He does not want me anymore, even the things that used to trigger him (the thought of me being with someone else for example), he's coping with them as he is rather no longer with me.

I'm freaking out. The pain of this reality is hitting me like a brick and my first reaction is to either to want to numb that pain with drugs, or try to 'take control'  over the situation by sleeping with someone else.. "That'll show him, now I'm truly no longer his", because I am mad. Mad my heart still belongs to him and he decided he does not want it anymore.

Whats the line between coping and selfdestructive behaviour? 

I wish he would want me again, but I cant focus my energy on getting him back. I talked to him, its pointless.

What do I do? How do I cope? I'm so utterly lost and depressed right now, he truly is the love of my life.

Please help.

Give me the gist of the text in a nutshell
<bot>: I'm afraid that the freight train of sadness over being dumped may lead me to a path of self-destructiveness, but feel helpless and don't know how to handle this
