Wow! I think we were all doing a little hollywood-esque fist in the air-go girl! type thing while reading that!
Its so amazing that you had the grace to hold yourself back so long, clearly, she had it coming.
I had a complete nightmare with my husbands ex girlfriend for years after they split up. They only went out for about 2 summers, going home for the winters, but he moved permanently down to where I live when he started to see me. She'd come back into our lives at various points, & we guessed this was probably when she had broken up with a boyfriend. But every time it was a nightmare! Phone calls at all hours, weird letters, messages on our answer machine declaring undying love for him, then calling back a few seconds later in tears begging him to pick the phone up, then the next minute, writing more letters exclaiming what a great night she had had with him & how great
it had been with him again etc, all really evil, vicious things designed to make me upset & throw him out. But she should have done her research better.... On several of the occasions he was supposedly with her he was actually with me. no question. I know this for a fact, because one of the days had been my birthday & we had gone away to celebrate it. She would just make up all sorts of bizzare stuff, & say things like she'd been speaking to his parents & how they had told her they wished he had never split up with her etc. all things again, that just weren't true. She would turn up at my work & send her friends to my work & then get her friends to ask my husband (then boyf at the time) when he was going to get back together with her & tell lies about me, like how they'd seen me getting into some mans car etc. But worst of all, she used to come round to our apartment & hammer on the door all night. ALL night! this was more than 4 years after they had split up!! It was just weird! she was rapidly turning into the stalker from hell!
I had been trying to find a away to keep the higher ground & not loose my composure, I didn't want her for one second to think she was getting to me or affecting our relationship. And one day it came! ahhh, blessed day!
I had orchestrated a sort of move away from my husbands old aquaintances (not his good mates, but just the casual ones who knew her) so we weren't in any direct contact with people who knew her. but she found us, the calls & letters again, after a silent period of about 6 months. In this time we had gotten married, but clearly, she didn't know this. A christmas card came, addressed to my husband, I recognised the writing right away. Inside it said;
To M(my DH's name) & your girlfriend, Merry Christmas from her name.
so I crossed out 'girlfriend', wrote wife & sent it back to her. We never heard from her again.
It felt soo good that I hadn't be forced to resort to sinking to her level but by golly! there were plenty of times when nothing, absolutely nothing would have given me more satisfaction! I do regret not being able to see her face as I dressed her down, that would have been priceless.....
Clearly, I have nothing on your horrendous experience, but I do sympathise. Hey, if any of you gals need help with revenge ideas just let me know, I thought up plenty to use on her.......
