<human>: Recently broke up with my emotionally abusive boyfriend of 1.5 years. We live together in an apartment and neither of us can move until one of us can save money to get into a new place. It was a mutual decision (aka blowout fight) to end things, but we're coping in very different ways. It's been about a week since the final breakup.

He's been out until extremely late for the past 4 nights and I only recently realized that he's been at the bar getting drunk. He made a comment about not knowing how some girls numbers got into his phone, to give you an idea how drunk he is. I confronted him and asked him to please not bring anyone home because I couldn't handle it and to please call me if he needed a ride. He responded by getting defensive and saying that I was the "last fucking person he would call". I'm afraid that he's masking his emotions with anger and alcohol, possibly wanting something bad to happen from his drinking and driving. He's got a history of depression, signs of bipolar disorder, and extreme anger issues. He doesn't know how to cope with anything.

I'm literally the only one in a 100 mile radius that he COULD call if he needed a DD, and he's too stubborn to call me. How can I make sure he doesn't kill himself/ someone else by being an idiot and driving home drunk from the bar every night?

Summarize the given text in a few sentences.
<bot>: My ex is coping with the breakup by drinking at the bar every night for the past week, drives himself home. I'm the only option for him to have a DD but he won't call me. Help?
