Ooooh, oooh, me, me...my H had a crazy ex-roommate!!
Well...I think I've mentioned we had to lie to xrm to get her to go away. (H finally told her I was pregnant--no calls in two weeks!!! According to H, the look on her face was priceless. )
I stayed out of it. I think it was the best thing. Anything from me, IMHO, would have only made matters worse. The *one* time I talked to her on the phone, I politely told her H was not available--and she later told H that I was rude to her. (He had been standing right there.) In my case, I honestly think more involvement from me would have only encouraged her--to "fight" for "her" guy. I think she truly needed to hear it from him.
Now, if she had shown up at my apartment or my work or called me...that would have been a different game. I would have ended it, my way, and she wouldn't have like it one bit. (Legal action!) But, I honestly think, I needed to let H handle it. For one, I don't think she would have gone away if she hadn't heard it from him. And two...well...it was more chances for H to see what she was really like.
