my drunken Valentine friend

My phone rang every half hour & even less throughout the weekend from one person. My friend living in New Jersey is in trouble......again. We've been friends since I was 19, I grew up, (to some extent) and he did not. In our late teens, he was incredibly aggressive, e.g. bar room brawls, DWIs, pissing in front of a court house, etc. He was once a real looker & ladies' man. Before he got knifed in the face & punched out so much, his facial features are now crooked. He had to lie & claim to be suicidal to get detox treatment cause he had no insurance.
He was in and out of rehabs. He's the typical Dr Jekyll and Mr Hyde. Friendly, helpful and very considerate sober & raging explosively when drunk. He moved, married and had three children over the course of years, we still kept in touch, but distance kept us from being best buddies anymore.
He is facing jail time and divorce, drinking heavily. My efforts failed from the beginning to help him at all. I still try. He needs mental assessment & treatment loads more than jail. I mean this a guy 0f 40 with the mind of an adolescent.
That was my weekend, answering constant calls to a drunken, senseless, raging friend and that is the purpose of friendship, right? to be there, no matter what.
