This guy would be kicked to the curb by anyone except someone who sadly believes she can love him out of being an addictive, abusive bastard.
That's only in Harlequin Romances, hon...bad boys tend to stay bad boys unless they seriously want to quit and do a lot of work to not be abusive,drunken hot headed bastards.
Love doesn't conquer all...unless it's loving yourself enough not to be self destructive. My personal experience is that addictive personalities who can't find something else to live for end up alone. No one else can put up with their crap forever. Some of them choose to be alone because relationships never work out for them and they never figure out why, so it's just easier to be alone, even if they get sober.
My brother is like that...he'd just rather not, he admits that the only women he's attracted to are as addicted and abusive as he once was. Women without issues do nothing for him, he's always attracted to women who have issues like my mother, which is one of those "Man, freud would have a field day with you, dude!" things.
At least he knows it. His last three girlfriends, (non JWs, although he professes to be one, but doesn't live it much) were all addictive personalities with strong OCD issues...just like my mother.
