sorry you are going through this. seems like you may have learned a hard lesson. i've learned quite a few of them myself. in my experience, i found that sometimes is best to let old dogs rest.
i remember at times when my rah and i were seperated that i would obsess with how he was doing and sometimes i just couldn't resist calling for one reason or another, i admit, i have even made up excuses to call knowing that my motives were not exactly pure and boy did i hate i called. not saying that this is what happened with you at all, just remembering the times when i found out the hard way that somethings are better left undone and unsaid. it can cause more harm that good
i think that she was kind of insensitive about calling you at the job and all, but guess what, she's addict and sometimes addicts don't think sensibly. hope that thing are going well at the job, in spite of all.
