Hey Funky... so sorry to hear this.
I too have been having suspicions that ABF was using again... he didn't even admit it to me, and I decided this weekend to break it off. His constant "trouble" is really making me concerned about my own safety and my career as well... if he needs to abuse substances so very bad, then it is also possible that he could throw me under the bus, you know? And there are lots of people who wouldn't want a person whose significant other is a drug user dealing with their confidential, personal financial and legal information... and I respect that.
I guess bottom line was I loved him, but I couldn't risk all of the things I had worked for for this relationship, because this relationship can't pay me or feed me or all of the other things that I would need if I couldn't work... but I still feel like my heart has been ripped out.
So... who knows. I guess you have to decide what you can live with and what you can't live with, right?
