Welcome!!!
Yeah, I was involved with a crack addict/alcoholic for over 3 1/2 years, never got robbed, unless you count my Macbook disappearing, but I acquired an std, gave away a lot of time, money and self esteem. I could make that statement, I love her very much, but at the end of the day, she's still a crack addict/alcoholic, wouldn't matter how much I loved her, how much I did for her, she'd still be a crack addict/alcoholic. And she would still be doing the things that crack addicts/alcoholics do.
She can be an incredibly warm, loving, and caring individual at times, but that thing-the addiction-trumps all and you end with a monster in human form. A monster that will consume everything in it's path. A monster that you can't fight.
The only advice I would give anyone involved with someone in active addiction, walk away, and don't look back. Sucks, but just what it is.
