I use vampirequeen on other forums too. When I was with ex I joined a mental health support group using a family nickname. I used the group to vent and had several threads including one called 'One hundred things I hate about my husband but am too scared to say'. Number one was 'I hate the way you breathe' lol. Anyway to cut a long story short my ex hacked my desktop, read my posts and, after I left him, joined the forum pretending to be a woman. He then printed off my posts and threatened to send them to my mum, my employer and anyone else he could think of.
The moderators blocked his isp and deleted all my posts. I was going to leave but I needed their support. Also he had cut me off from everyone in the real world when we were married and I was buggered if he was going to control me after I'd escaped. So me and a druggie, cross dressing schizophrenic (he was lovely) chose a name that we thought ex would never link to me. As I was a very conservatively dressed, middle aged, Catholic school teacher we chose vampirequeen.
Oddly over the years I have grown into my name, mainly during my Jezebel period. Now I can't imagine being anyone else lol.
