>why she went to america in the first place?
You clearly have not been on here for very long.
She moved in with a guy, Dana, who she actually met on here. Or well - he came here. He "joined" the community and then managed to get in touch with her. He posted on pre-wipe Bounceme as Darrin Floen and later as ColourWatch. At that time, in 2007, she was still with some internet creeper who was in his thirties or something. They played a lot of WoW together and in the beginning of 2008 she went to Boston to visit him. At some point she left the other guy. For all we know she stayed with Dana in Boston and Oxford. Both of them were still in touch with various members of the "community" back then, but in the end of 2008 they disappeared from WoW and the internet in general. It seems that Ms. Olivia was somewhat ashamed of being with one of her "fans" and word about that got out. She may also have been annoyed by the harassment on WoW.
They may or may not be still together, nobody knows. If they have married or not - who cares. The only reason I could imagine would be immigration issues.
