Both of them were absolutely drunk. My bf and his friend are good friends, but live about 1600km apart. Our friend travels quite a bit, so we do get together regularly.

I ended up having to phone my bf's mom at midnight (she stays in the same block as we do) as I could not control him anymore. Yes, I felt like a right idiot, but I was in a position where I just about had to decide whether to give them the car keys, or I was going to drive off - anything as long as I didn't have to be near him.
Luckily his mom is really understanding, she woke up to meet me. My bf and his friend I just left in the car, it was unlocked, as was the garage and we were inside our safe complex so they'd be fine. I had a smoke with the Mom in law and she offered me a cup of coffee, but all i wanted to do was sleep. 10 minutes my later my bf staggered into her lounge (Still not sure why he went there instead of our apartment??) crashed on the couch and that was the end of that. I went to our apartment and took whatever sleeping pills and anti-anxiety tabs I could. But i was scared that he'd come up in the middle of the night - he has not often been aggressive towards me, so this was quite out of character, but it scared me. and I don't know what to expect tonight.
He is a father of 2 children - neither of which stay with him - why does he act like a maniac!?

8 days prior we both went for a quick drink after work with another friend of his. I left after 1 hour and he promised he'd be right behind me. He should have been home at +-7PM, instead gets home at around 2AM, and turns out he'd gone to strip club too.

I've tried to explain to him that I am a whole lot more sensitive, that things like this create immense anxiety in me and cause me to spiral into deep depression, sometimes with suicidal thoughts. The day afterwards he's an amazing bf, but he soon goes back to being his old self.
Please dont get me wrong - I don't feel he's an alchoholic, just on average once a month or so he really loses the plot and I follow suit (Emotionally). Right now I am going through suicidal thoughts (Luckily I try rationalise things) and feel terrible
