I need strength and prayers...UPDATE

My boyfriend is coming off of drugs. He has tried to attack me today and as a result there is a hole in my bedroom door. I'm 7 months pregnant. He hasn't slept in 48 hours and is becoming delusional. He said if I call 911 he's going to kill himself. That there will be a standoff/shoot out with the police

Well, I've given him hours to leave without me calling 911.

Now I have to. I'm so scared. Please let this end with him still alive. I have to do this for my daughter... please pray for me.

UPDATE:

Thank you all so much for your prayers. I believe they helped immensely. I had my peer support specialist come over to help me make the call. We were texted by a deputy to meet them a couple blocks away from the house. I explained everything. He said "there is nothing we can do." My jaw dropped and I almost cussed him out. If I call the police for help, it'd BAD. He said I would have to legally evict him (even though he doesn't live here) and ask for a restraining order. All while I was away, he overdosed. As I walked in he was convulsinf so bad that the downstairs neighbor was banging on their ceiling, kind of like "hey shut up" (good to know because I have epilepsy so if I have a seizure they're just going to get mad?). I stayed calm. He was unresponsive. I called 911 and administered a dose of Narcan. I always have it on hand, even though I don't use, I am around people who do when I leave my house to get my medication and I've saved lives with it before. He was still unresponsive but I didn't want to give him another dose in case he woke up swinging. I put him on his side in case he threw up and waited for EMS. They took him to the hospital and as I cleaned up I found all the drugs. Over 20 xanax Bara, meth, coke, heroin and fentanyl. Later on his parents updated me that he might not make it. Longer story short, he made it. His family and I made the decision that rehab wouldn't help, he'd been a million times and with delivery being so close we don't have time to waste. He's currently back here with me, resting. When he wakes up we are going to have a big talk and I have a lot of rules in place. His family and I decided that if he fucks up even 1 more time, they will come get him and deal with it. I'm still not sure if I've made the right choice. Please, try not to judge me too harshly.
